b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

d1de6d6c63 soc: qcom: Remote filesystem memory driver
The Qualcomm remote file system protocol is used by certain remoteprocs,
in particular the modem, to read and write persistent storage in
platforms where only the application CPU has physical storage access.

The protocol is based on a set of QMI-encoded control-messages and a
shared memory buffer for exchaning the data. This driver implements the
latter, providing the user space service access to the carved out chunk
of memory.

This commit adds support for the Broadcom STB S2/S3/S5 suspend
states on MIPS based SoCs.

This requires quite a lot of code in order to deal with the
different HW blocks that need to be quiesced during suspend:

- DDR PHY
- DDR memory controller and arbiter
- control processor

The final steps of the suspend execute in cache and there is is a little
bit of assembly code in order to shut down the DDR PHY PLL and then go
into a wait loop until a wake-up even occurs. Conversely the resume part
involves waiting for the DDR PHY PLL to come back up and resume
executions where we left.

0b741b8234 soc: bcm: brcmstb: Add support for S2/S3/S5 suspend states (ARM)
This commit adds support for the Broadcom STB S2/S3/S5 suspend states on
ARM based SoCs.

This requires quite a lot of code in order to deal with the different HW
blocks that need to be quiesced during suspend:

- DDR PHY SHIM
- DDR memory controller and sequencer
- control processor

The final steps of the suspend execute in an on-chip SRAM and there is a
little bit of assembly code in order to shut down the DDR PHY PLL and
then go into a wfi loop until a wake-up even occurs. Conversely the
resume part involves waiting for the DDR PHY PLL to come back up and
resume executions where we left.

For S3, because of our memory hashing (actual hashing code not included
for simplicity, and is bypassed) we need to relocate the writable
variables (stack) into SRAM shortly before suspending in order to leave
the DRAM untouched and create a reliable hash of its contents.

This code has been contributed by Brian Norris initially and has been
incrementally fixed and updated to support new chips by a lot of people.

126534141b MIPS: lantiq: Add a GPHY driver which uses the RCU syscon-mfd
Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of

c20b3b8019 MIPS: lantiq: Convert the fpi bus driver to a platform_driver
Instead of hacking the configuration of the FPI bus into the arch code
add an own bus driver for this internal bus. The FPI bus is the main
bus of the SoC. This bus driver makes sure the bus is configured
correctly before the child drivers are getting initialized. This driver
will probably also be used on different SoCs later.

ti_sci_pm_domains driver so because of this we see a NULL pointer

is attempted.

Give the genpd a name before registering it to avoid this.

8fed2ce98e drivers: soc: sunxi: add support for remapping func value to reg value
On some Allwinner SoCs, sometimes the value needed to write into the
register to claim SRAM is not equal to the value specified in the
device tree.

The device tree binding defines 0 as "mapped to CPU" and 1 as "mapped
to X device". This matches the value written to the configuration
register for the SRAM blocks currently supported. However, the not yet
supported VE SRAM block is claimed for the device by writing 0x7fffffff,
which is vastly different from the other blocks. On the A64, SRAM C is
claimed by the device by writing a 0, which is the opposite of the
current design.

Add a value remapping in sunxi_sram_func structure, and let the
sunxi_sram_of_parse function set the remapped register value.
This allows us to keep the convention currently used in the device tree
binding.

2262a65f0b drivers: soc: sunxi: fix error processing on base address when claiming
When claiming SRAM, if the base is set to an error, it means that the
SRAM controller has been probed, but failed to remap the controller
memory zone. If the base is zero, thus the SRAM controller should be not
probed at all, and it should return -EPROBE_DEFER. However, currently we
returned -EPROBE_DEFER in the former situation, and ignored the latter
situation (which will lead to the kernel to panic).

Fix the behavior on abnormal base address processing when claiming.

Add SCPSYS power domain driver for MT7622 SoC having four power domains
which are respectively ETHSYS for Ethernet including embedded switch,
WBSYS for WIFI and Bluetooth, HIF0SYS for PCI-E and SATA, and HIF1SYS for

corresponding function is no longer to use in order to reach more minimal
power dissipation.

9e01e2d56d soc: imx: gpcv2: fix regulator deferred probe
If a regulator requests a deferred probe, the power domain gets
initialized twice. This leads to a list double add (without
list debugging the kernel hangs due to the double add later):

  WARNING: CPU: 0 PID: 19 at lib/list_debug.c:31 __list_add_valid+0xbc/0xc4

Initialize the power domain after we get the regulator. Also do
not print an error in case the regulator defers probing.

not needed; the macro itself has no docstring and of_get_next_child()
used in the implementation begins with "Returns a node pointer with
refcount incremented" but then only at the very end of the docstring
the crucial part "Decrements the refcount of prev" is mentioned.)

e854711291 ARM: SoC driver updates
- New SoC specific drivers
   - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later)
     based on the "BPMP" firmware
   - Clocksource and system controller drivers for the newly added
     Action Semi platforms (both arm and arm64).
 
 - Reset subsystem, merged through arm-soc by tradition:
   - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini SoCs
   - Various subsystem-wide cleanups
 
 - Updates for existing SoC-specific drivers
   - TI GPMC (General Purpose Memory Controller)
   - Mediatek "scpsys" system controller support for MT6797
   - Broadcom "brcmstb_gisb" bus arbitrer
   - ARM SCPI firmware
   - Renesas "SYSC" system controller
 
 One more driver update was submitted for the Freescale/NXP DPAA
 data path acceleration that has previously been used on PowerPC
 chips. I ended up postponing the merge until some API questions
 for its unusual MMIO access are resolved.

The BPMP firmware, found on Tegra186 and later, provides an ABI that can
be used to enable and disable power to several power partitions in Tegra
SoCs. The ABI allows for enumeration of the available power partitions,
so the driver can be reused on future generations, provided the BPMP ABI
remains stable.

8be381a131 soc: renesas: Rework Kconfig and Makefile logic
The goals are to:
  - Allow precise control over and automatic selection of which
    (sub)drivers are used for which SoC,
  - Allow adding support for new SoCs easily,
  - Allow compile-testing of all (sub)drivers,
  - Keep driver selection logic in the subsystem-specific Kconfig,
    independent from the architecture-specific Kconfig (i.e. no "select"
    from arch/arm64/Kconfig.platforms), to avoid dependencies.

This is implemented by:
  - Introducing Kconfig symbols for all drivers and sub-drivers,
  - Introducing the Kconfig symbol SOC_RENESAS, which is enabled
    automatically when building for a Renesas ARM platform, and which
    enables all required drivers without interaction of the user, based
    on SoC-specific ARCH_* symbols,
  - Allowing the user to enable any Kconfig symbol manually if
    COMPILE_TEST is enabled,
  - Using the new Kconfig symbols instead of the ARCH_* symbols to
    control compilation in the Makefile,
  - Always entering drivers/soc/renesas/ during the build.

f538a82c07 ARM: SoC fixes (and a cross-arch dt-include fix)
We had a small batch of fixes before -rc1, but here is a larger one. It
 contains a backmerge of 4.12-rc1 since some of the downstream branches we
 merge had that as base; at the same time we already had merged contents
 before -rc1 and rebase wasn't the right solution.
 
 A mix of random smaller fixes and a few things worth pointing out:
 
  - We've started telling people to avoid cross-tree shared branches if all
    they're doing is picking up one or two DT-used constants from a
    shared include file, and instead to use the numeric values on first
    submission. Follow-up moving over to symbolic names are sent in right
    after -rc1, i.e. here. It's only a few minor patches of this type.
 
  - Linus Walleij and others are resurrecting the 'Gemini' platform, and
    wanted a cut-down platform-specific defconfig for it. So I picked that
    up for them.
 
  - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it helps
    people to prepare patches since it's a pain when defconfig and current
    savedefconfig contents differs too much.
 
  - Devicetree additions for some pinctrl drivers for Armada that were
    merged this window. I'd have preferred to see those earlier but it's not
    a huge deail.
 
 The biggest change worth pointing out though since it's touching other
 parts of the tree: We added prefixes to be used when cross-including
 DT contents between arm64 and arm, allowing someone to #include
 <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
 arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
 resulted in a recursive symlink.
 
 Instead, I've now moved it out of arch/*/boot/dts/include, into a shared
 location under scripts/dtc. While I was at it, I consolidated so all
 architectures now behave the same way in this manner.
 
 Rob Herring (DT maintainer) has acked it. I cc:d most other arch
 maintainers but nobody seems to care much; it doesn't really affect them
 since functionality is unchanged for them by default.

e23c7f7d57 soc: imx: add PM dependency for IMX7_PM_DOMAINS
The new pm domain driver causes a build failure when CONFIG_PM
is not set:

warning: (IMX7_PM_DOMAINS) selects PM_GENERIC_DOMAINS which has unmet direct dependencies (PM)
drivers/base/power/domain_governor.c: In function 'default_suspend_ok':
drivers/base/power/domain_governor.c:75:17: error: 'struct dev_pm_info' has no member named 'ignore_children'

This adds a dependency to ensure that we don't attempt to build the
driver without CONFIG_PM.

In commit 461a6946b1 ("iommu: Remove pci.h include from

include in this driver, manifesting as:

    CC      drivers/soc/fsl/qbman/qman_portal.o
    drivers/soc/fsl/qbman/qman_portal.c: In function 'qman_portal_probe':

        if (dma_set_mask(dev, DMA_BIT_MASK(40))) {
        ^

on the corenet32_smp_defconfig (and 64 bit respectively.)  The above
commit was singled out via git bisect.

The header it was implictly relying on getting was dma-mapping.h - so
we explicitly add it here.

e21c7316d8 soc/fsl/qbman: Disable IRQs for deferred QBMan work
Work for Congestion State Notifications (CSCN) and Message Ring (MR)
handling is handled via the workqueue mechanism. This requires the
driver to disable those IRQs before scheduling the work and re-enabling
it once the work is completed so that the interrupt doesn't continually
fire.

e5c5c8d23f soc/fsl/qe: only apply QE_General4 workaround on affected SoCs
The QE_General4 workaround is only valid for the MPC832x and MPC836x
SoCs. The other SoCs that embed a QUICC engine are not affected by this
hardware bug and thus can use the computed divisors (this was
successfully tested on the T1040).

Similalry to what was done in commit 8ce795cb0c ("i2c: mpc: assign the
correct prescaler from SVR") in order to avoid changes in
the device tree nodes of the QE (with maybe a variant of the compatible
property), the PVR reg is read out to find out if the workaround must be
applied or not.

2ccf80b756 soc/fsl/qe: round brg_freq to 1kHz granularity
Because of integer computation rounding in u-boot (that sets the QE
brg-frequency DTS prop), the clk value is 99999999 Hz even though it is
100 MHz.

When setting brg clks that are exact divisors of 100 MHz, this small
differnce plays a role and can result in lower clks to be output (for
instance 20 MHz - divide by 5 - results in 16.666 MHz - divide by 6).

This patch fixes that by "forcing" the brg_clk to the nearest kHz when
the difference is below 2 integer rounding errors (i.e. 4).

Power area A2VC0 was removed in revision ES2.0, cfr. R-Car Gen3 Hardware
User's Manual rev. 0.53E.

Hence remove it from the power area table when not running on ES1.x.

This is in line with the goal to:
  1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
     for now,
  2. Make it clear which code supports ES1.x, so it can easily be
     identified and removed later, when production SoCs are deemed

afa6f53df6 soc: renesas: rcar-sysc: Add support for fixing up power area tables
The same SoC may have different power areas, depending on SoC revision.
One option is to use different sets of power area tables for each SoC
revision.  However, if the differences are small, it is much more
space-efficient to have a single set of tables, and fix those up at
runtime instead.

Hence provide a helper to NULLify power areas that do not exist on some
revisions (NULLified power areas are skipped during the registration
phase), and support for an optional initialization callback to e.g. fix
up power area tables.

On i.MX6QP, due to hardware erratum ERR009619, the PRE clocks may be
stalled during the power up sequencing of the PU power domain. As this
may lead to a complete loss of display output, the recommended
workaround is to keep the PU domain enabled during normal system
operation.

Implement this by rejecting the domain power down request on the
affected SoC.

52835d59fc soc: ti: Add ti_sci_pm_domains driver
Introduce a ti_sci_pm_domains driver to act as a generic pm domain
provider to allow each device to attach and associate it's ti-sci-id so
that it can be controlled through the TI SCI protocol.

This driver implements a simple genpd where each device node has a
phandle to the power domain node and also must provide an index which
represents the ID to be passed with TI SCI representing the device using
a single phandle cell. The driver manually parses the phandle to get the
cell value. Through this interface the genpd dev_ops start and stop
hooks will use TI SCI to turn on and off each device as determined by
pm_runtime usage.

1fd09e5d88 soc/tegra: Add initial flowctrl support for Tegra132/210
Tegra132 and Tegra210 support the flowctrl module and so add initial
support for these devices.

Please note that Tegra186 does not support the flowctrl module, so
update the initialisation function such that we do not fall back and
attempt to map the 'hardcoded' address range for Tegra186. Furthermore
64-bit Tegra devices have always had the flowctrl node defined in their
device-tree and so only use the 'hardcoded' addresses for 32-bit Tegra
devices.

7e10cf7436 soc/tegra: Move Tegra flowctrl driver
The flowctrl driver is required for both ARM and ARM64 Tegra devices
and in order to enable support for it for ARM64, move the Tegra flowctrl
driver into drivers/soc/tegra.

By moving the flowctrl driver, tegra_flowctrl_init() is now called by
via an early initcall and to prevent this function from attempting to
mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()'
is also added.

1859217bec soc: tegra: make fuse-tegra explicitly non-modular
The Makefiles currently controlling compilation of this code is:

drivers/soc/tegra/Makefile:obj-y += fuse/
drivers/soc/tegra/fuse/Makefile:obj-y += fuse-tegra.o

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

3a317f5235 soc: imx: gpc: fix the wrong using of regmap cache
Without providing the proper reg_defaults, the regmap registers first
read out may be always 0 if enabling cache, which results in the
following issue we met.
e.g. During driver probe in imx6_pm_domain_power_on():
regmap_read(pd->regmap, pd->reg_offs + GPC_PGC_PUPSCR_OFFS, &val);
The PGC_PUPSCR register val is always 0 but it's actually 0xf01 in HW.

Since GPC registers are tightly related to CPU bring up and may be
changed in bootloader, we don't want to provide defaults.
And the cache really does not save too much for GPC module.

Therefore, simply disable cache to fix the issue and make life easy.

a0ebf66267 soc: samsung: Do not build ARMv7 PMU drivers on ARMv8
The Exynos Power Management Unit (PMU) drivers contain quite large
static arrays of register values necessary for given Exynos SoC to enter
low power mode.  All this data is useless for ARMv8 SoC like
Exynos5433, because the image will not be shared between ARMv7 and
ARMv8.

Add additional Kconfig symbol for selecting the SoC-specific driver
addons thus skipping the useless data in the final image (this is
similar approach to chosen for Exynos clock controller drivers):
 - exynos-pmu driver will be compiled on both architectures ARMv7
   and ARMv8,
 - additional driver_data for ARMv7 SoCs will not be built on ARMv8
   and a macro will return NULL for them in of_device_id - this should
   be safe as these compatibles cannot match on ARMv7 and driver
   anyway handles NULL driver_data,
 - on ARMv8 compile only exynos-pmu driver which exposes the
   syscon-regmap for PMU address space.

721cabf6c6 soc: imx: move PGC handling to a new GPC driver
This is an almost complete re-write of the previous GPC power gating control
code found in the IMX architecture code. It supports both the old and the new
DT binding, allowing more domains to be added later and generally makes the
driver easier to extend, while keeping compatibility with existing DTBs.

As the result, all functionality regarding the power gating controller
gets removed from the IMX architecture GPC driver.  It keeps only the
IRQ controller code in the architecture, as this is closely coupled to
the CPU idle implementation.

b2e3c4319d ARM: SoC driver updates
Driver updates for ARM SoCs.
 
 A handful of driver changes this time around. The larger changes are:
 
  - Reset drivers for hi3660 and zx2967
  - AHCI driver for Davinci, acked by Tejun and brought in here due to
    platform dependencies
  - Cleanups of atmel-ebi (External Bus Interface)
  - Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
    register range on the SoCs)
  - PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)

6ae52c65e0 ARM: SoC platform updates
In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
 C code changes for SoC platforms. This release cycle the diffstat is quite
 nice, in that we're removing 3x the amount of code that's being added.
 
 The main reason for this is that there's a removal of camera drivers for
 Freescale i.MX chips (driver was removed so the device registration isn't
 needed any more). There's also removal of display initialization code for OMAP
 that is no longer needed.
 
 The rest are mostly minor tweaks and cleanups; constification on Samsung
 platforms, cleanup of ux500 platform data, purge of other unused platform
 data/device seutp on i.MX and other good stuff.
 
 New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

a3919caaa2 remoteproc updates for v4.11
This introduces support for booting the dedicated sensor core in the
 Qualcomm MSM8996, updates the Qualcomm ADSP and Hexagon drivers to
 utilize SMD subdevice helpers for properly handle shutdowns and restarts
 of the remoteproc, add virtio support to the ST remoteproc and refactor
 the Qualcomm Hexagon driver to handle variations between platforms.
 
 The support code for parsing, loading and authenticating Qualcomm
 firmware files (MDT) is refactored and move to drivers/soc/qcom, to
 allow for non-remoteproc drivers to utilize this.
 
 Finally it brings some cleanups to the remoteproc core.

01625cc5e6 remoteproc: qcom: mdt_loader: Use signed type for offset
In the transition from using rproc_da_to_va(), the type of the load
offset became unsigned. This causes the subsequent check to let negative
values less than p_memsz + mem_size through and we write outside of the
buffer.

Change the type back to a signed value to catch this.

b13b2330aa soc: samsung: pm_domains: Read domain name from the new label property
Device tree nodes for each power domain should use generic "power-domain"
name, so using it as a domain name doesn't give much benefits. This patch
adds support for human readable names defined in 'label' property. Such
names are visible to userspace and makes debugging much easier. When no
'label' property is found, driver keeps using the name constructed from
full node name.

4c58063d42 soc: rockchip: add driver handling grf setup
The General Register Files are an area of registers containing a lot
of single-bit settings for numerous components as well full components
like usbphy control. Therefore all used components are accessed
via the syscon provided by the grf nodes or from the sub-devices
created through the simple-mfd created from the grf node.

Some settings are not used by anything but will need to be set up
according to expectations on the kernel side.

Best example is the force_jtag setting, which defaults to on and
results in the soc switching the pin-outputs between jtag and sdmmc
automatically depending on the card-detect status. This conflicts
heavily with how the dw_mmc driver expects to do its work and also
with the clock-controller, which has most likely deactivated the
jtag clock due to it being unused.

So far the handling of this setting was living in the mach-rockchip
code for the arm32-based rk3288 but that of course doesn't work
for arm64 socs and would also look ugly for further arm32 socs.

Also always disabling this setting is quite specific to linux and
its subsystems, other operating systems might prefer other settings,
so that the bootloader cannot really set a sane default for all.

So introduce a top-level driver for the grf that handles these
settings that need to be a certain way but nobody cares about.

Other needed settings might surface in the future and can then
be added here, but only as a last option. Ideally general GRF
settings should be handled in the driver needing them.

de399813b5 powerpc updates for 4.10
Highlights include:
 
  - Support for the kexec_file_load() syscall, which is a prereq for secure and
    trusted boot.
 
  - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
 
  - Sort the exception tables at build time, to save time at boot, and store
    them as relative offsets to save space in the kernel image & memory.
 
  - Allow building the kernel with thin archives, which should allow us to build
    an allyesconfig once some other fixes land.
 
  - Build fixes to allow us to correctly rebuild when changing the kernel endian
    from big to little or vice versa.
 
  - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
 
  - Initial stack protector support (-fstack-protector).
 
  - Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
 
  - Fix an oops in cxl coredump generation when cxl_get_fd() is used.
 
  - Freescale updates from Scott: "Highlights include 8xx hugepage support,
    qbman fixes/cleanup, device tree updates, and some misc cleanup."
 
  - Many and varied fixes and minor enhancements as always.

Merge tag 'powerpc-4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:
 "Highlights include:

   - Support for the kexec_file_load() syscall, which is a prereq for
     secure and trusted boot.

   - Prevent kernel execution of userspace on P9 Radix (similar to
     SMEP/PXN).

   - Sort the exception tables at build time, to save time at boot, and
     store them as relative offsets to save space in the kernel image &
     memory.

   - Allow building the kernel with thin archives, which should allow us
     to build an allyesconfig once some other fixes land.

   - Build fixes to allow us to correctly rebuild when changing the
     kernel endian from big to little or vice versa.

   - Plumbing so that we can avoid doing a full mm TLB flush on P9
     Radix.

   - Initial stack protector support (-fstack-protector).

   - Support for dumping the radix (aka. Linux) and hash page tables via
     debugfs.

   - Fix an oops in cxl coredump generation when cxl_get_fd() is used.

   - Freescale updates from Scott: "Highlights include 8xx hugepage
     support, qbman fixes/cleanup, device tree updates, and some misc
     cleanup."

   - Many and varied fixes and minor enhancements as always.

991688bfc6 ARM: SoC driver updates for v4.10
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting

3ec5e8d82b ARM: SoC non-urgent fixes for v4.10
As usual, we queue up a few fixes that don't seem urgent enough to go in
 through -rc, or that just came a little too late given their size.
 
 The zx fixes make the platform finally boot on real hardware, the
 davinci and imx31 get the DT support working better for some of
 the machines that are still normally used with classic board files.
 One tegra fix is important for new bootloader versions, but the
 bug has been around for a while without anyone noticing.
 
 The other changes are mostly cosmetic.

b8d2798f32 This is a fairly quiet release. We don't have any patches to the core
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)
  - i.MX imx6ull
  - Socionext's UniPhier SoC CPUs
  - Mediatek MT2701 SoCs
  - Rockchip rk1108 SoCs
  - Qualcomm MSM8994/MSM8992 SoCS

5233c331cf It's been an busy period for mmc. Quite some changes in the mmc core, two new
mmc host drivers, some existing drivers being extended to support new IP
 versions and lots of other updates.
 
 MMC core:
  - Delete eMMC packed command support
  - Introduce mmc_abort_tuning() to enable eMMC tuning to fail gracefully
  - Introduce mmc_can_retune() to see if a host can be retuned
  - Re-work and improve the sequence when sending a CMD6 for mmc
  - Enable CDM13 polling when switching to HS and HS DDR mode for mmc
  - Relax checking for CMD6 errors after switch to HS200
  - Re-factoring the code dealing with the mmc block queue
  - Recognize whether the eMMC card supports CMDQ
  - Fix 4K native sector check
  - Don't power off the card when starting the host
  - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
  - Improve error handling and drop meaningless BUG_ONs()
  - Lots of clean-ups and changes to improve the quality of the code
 
 MMC host:
  - sdhci: Fix tuning sequence and clean-up the related code
  - sdhci: Add support to via DT override broken SDHCI cap register bits
  - sdhci-cadence: Add new driver for Cadence SD4HC SDHCI variant
  - sdhci-msm: Update clock management
  - sdhci-msm: Add support for eMMC HS400 mode
  - sdhci-msm: Deploy runtime/system PM support
  - sdhci-iproc: Extend driver support to newer IP versions
  - sdhci-pci: Add support for Intel GLK
  - sdhci-pci: Add support for Intel NI byt sdio
  - sdhci-acpi: Add support for 80860F14 UID 2 SDIO bus
  - sdhci: Lots of various small improvements and clean-ups
  - tmio: Add support for tuning
  - sh_mobile_sdhi: Add support for tuning
  - sh_mobile_sdhi: Extend driver to support SDHI IP on R7S72100 SoC
  - sh_mobile_sdhi: remove support for sh7372
  - davinci: Use mmc_of_parse() to enable generic mmc DT bindings
  - meson: Add new driver to support GX platforms
  - dw_mmc: Deploy generic runtime/system PM support
  - dw_mmc: Lots of various small improvements
 
 As a part of the mmc changes this time, I have also pulled in an immutable
 branch/tag (soc-device-match-tag1) hosted by Geert Uytterhoeven, to share the
 implementation of the new soc_device_match() interface. This is needed by the
 below mmc related changes:
  - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
  - soc: fsl: add GUTS driver for QorIQ platforms

Merge tag 'mmc-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc

Pull MMC updates from Ulf Hansson:
 "It's been an busy period for mmc. Quite some changes in the mmc core,
  two new mmc host drivers, some existing drivers being extended to
  support new IP versions and lots of other updates.

  MMC core:
   - Delete eMMC packed command support
   - Introduce mmc_abort_tuning() to enable eMMC tuning to fail
     gracefully
   - Introduce mmc_can_retune() to see if a host can be retuned
   - Re-work and improve the sequence when sending a CMD6 for mmc
   - Enable CDM13 polling when switching to HS and HS DDR mode for mmc
   - Relax checking for CMD6 errors after switch to HS200
   - Re-factoring the code dealing with the mmc block queue
   - Recognize whether the eMMC card supports CMDQ
   - Fix 4K native sector check
   - Don't power off the card when starting the host
   - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
   - Improve error handling and drop meaningless BUG_ONs()
   - Lots of clean-ups and changes to improve the quality of the code

  MMC host:
   - sdhci: Fix tuning sequence and clean-up the related code
   - sdhci: Add support to via DT override broken SDHCI cap register
     bits
   - sdhci-cadence: Add new driver for Cadence SD4HC SDHCI variant
   - sdhci-msm: Update clock management
   - sdhci-msm: Add support for eMMC HS400 mode
   - sdhci-msm: Deploy runtime/system PM support
   - sdhci-iproc: Extend driver support to newer IP versions
   - sdhci-pci: Add support for Intel GLK
   - sdhci-pci: Add support for Intel NI byt sdio
   - sdhci-acpi: Add support for 80860F14 UID 2 SDIO bus
   - sdhci: Lots of various small improvements and clean-ups
   - tmio: Add support for tuning
   - sh_mobile_sdhi: Add support for tuning
   - sh_mobile_sdhi: Extend driver to support SDHI IP on R7S72100 SoC
   - sh_mobile_sdhi: remove support for sh7372
   - davinci: Use mmc_of_parse() to enable generic mmc DT bindings
   - meson: Add new driver to support GX platforms
   - dw_mmc: Deploy generic runtime/system PM support
   - dw_mmc: Lots of various small improvements

  As a part of the mmc changes this time, I have also pulled in an
  immutable branch/tag (soc-device-match-tag1) hosted by Geert
  Uytterhoeven, to share the implementation of the new
  soc_device_match() interface. This is needed by these mmc related
  changes:

   - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
   - soc: fsl: add GUTS driver for QorIQ platforms"

34c1c21e94 soc: fsl: fix section mismatch build warnings
We get the following warning with the driver is compiled in:

WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'

With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported:

WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the
function fsl_guts_probe() to the function
.init.text:of_flat_dt_get_machine_name()
The function fsl_guts_probe() references
the function __init of_flat_dt_get_machine_name().
This is often because fsl_guts_probe lacks a __init
annotation or the annotation of of_flat_dt_get_machine_name is wrong.

This patch fixes the issue by using the normal DT/OF API rather than
the of_flat_* one.
