b88a107654 Merge branch 'v4.11/fixes-non-critical' into v4.11/soc
This merge is because patches in branch v4.11/soc conflict
with cleanup done as part of 0a5011673a ("ARM: davinci:
da850: coding style fix") that is already queued as a
non-critical fix.

b40881738f ARM: davinci: da850: fix da850_set_pll0rate()
This function is confusing - its second argument is an index to the
freq table, not the requested clock rate in Hz, but it's used as the
set_rate callback for the pll0 clock. It leads to an oops when the
caller doesn't know the internals and passes the rate in Hz as
argument instead of the cpufreq index since this argument isn't bounds
checked either.

Fix it by iterating over the array of supported frequencies and
selecting a one that matches or returning -EINVAL for unsupported
rates.

Also: update the davinci cpufreq driver. It's the only user of this
clock and currently it passes the cpufreq table index to
clk_set_rate(), which is confusing. Make it pass the requested clock
rate in Hz.

e79ab194d1 ARM: SoC platform updates for v4.10
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - Added support for the TI DRA71x family of SoCs in mach-omap2,
   this is an new variant of the the DRA72x/DRA74x automotive
   infotainment chips we already supported for a while.
 
 - Added support for the ST STM32F746 SoC, the first Cortex-M7
   based microcontroller we support, related to the smaller
   STM32F4 family.
 
 - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
   see http://elinux.org/RZ-G
 
 - SMP is now supported on the OX820 platform
 
 - A lot of code in mach-omap2 gets removed as a follow-up to
   removing support for board files in the previous release
 
 - Davinci has some new work to improve USB support
 
 - For i.MX, the performance monitor now supports profiling the
   memory controller using 'perf'
 
 Conflicts:
 arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init()
 is gone, calling of_clk_init(NULL) is sufficient now.

b5e1438cf9 ARM: davinci: da830-evm: use gpio descriptor for mmc pins
Currently the mmc driver is polling the gpio to know if the
card was removed.

By using a gpio descriptor instead of the platform callbacks,
the driver will be able to register the gpio using the mmc core
APIs designed for this purpose.

This has the advantage that an irq will be registered, and
polling is no longer needed. Also, a dependency on platform
callbacks is removed for this board.

CONFIG_SUSPEND might be enabled even when da850 support is not, causing
build failure:

arch/arm/mach-davinci/built-in.o: In function `davinci_pm_init':

36173c2d02 ARM: davinci: da850: Fix pwm name matching
This fixes pwm name matching for DA850 familiy devices. When using device
tree, the da850_auxdata_lookup[] table caused pwm devices to have the exact
same name, which caused errors when trying to register the devices.

We cannot have multiple entries for the same clock in in da850_clks[], so
we have added child clocks to the EHRPWM and ECAP LPSC clocks so that each
PWM device will have its own clock for proper name matching.

ced95ac081 ARM: davinci: da8xx: register USB PHY clocks in the DT file
The usb20_phy clock needs to be registered for the driver to be able
to get and enable a clock. Currently the usb phy clocks are registered
from board files, which will not be called during a device tree based
boot.

To be able to probe correctly usb form a device tree boot, register
the usb phy clocks from the DT specific init.

Unfortunately, davinci does not have proper clock support on device tree
yet, so by registering the clock from the DT specific file we are
forced to hardcode the parent clock, and cannot select refclkin as
parent for any of the phy clocks of the da850 family.

As none of the current da850 based boards currently in mainline use
refclkin as source. I guess we can live with this limitation until clocks
are correctly represented through CCF/device tree.

0004b02a68 ARM: davinci: da8xx: add usb phy clocks
Up to this point, the USB phy clock configuration was handled manually in
the board files and in the usb drivers. This adds proper clocks so that
the usb drivers can use clk_get and clk_enable and not have to worry about
the details. Also, the related code is removed from the board files and
replaced with the new clock registration functions.

This also removes the #if IS_ENABLED(CONFIG_USB_MUSB_HDRC) around the musb
declaration and renames the musb platform device so that we can reference
it from the usb20 clock even if the musb device is not used.

40a17abc8b ARM: davinci: da8xx: Add full regulator constraints for non-DT boot
The phy framework requests an optional "phy" regulator. If it does
not find one, it returns -EPROBE_DEFER. In the case of non-DT boot
for the omap138-lcdk board, this would prevent the usb11 phy to probe
correctly and ohci would not enumerate.

By calling regulator_has_full_constraints(), An error would be returned
instead of -EPROBE_DEFER for the regulator, and the probe of the phy driver
can continue normally without a regulator.

8f899b4ed6 ARM: davinci: da850: Add ti-aemif lookup for clock matching
The davinci boards don't have their clocks in DT yet and getting a clock
will fail, unless registering them as clk_lookups. This registers the
aemif clock for the ti-aemif memory driver.

The current aemif lookup entry resolving to the same clock:
    'CLK(NULL,               "aemif",        &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward
compatibility.

Currently the davinci boards only configure the AEMIF in case of non-DT
boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via
the ti-aemif memory driver code.

44524a010a ARM: dts: da850: Add basic DTS for the LCDK
The LCDK is the successor to the late Hawkboard.
Among the differences are the flash (16bits vs 8bits) and some pins
(MMC, LEDs, buttons, some external connectors), however the main
components remain the same (eth. phy, audio codec, video decoder and
DAC) except for the main PMIC, different and hard-wired on the LCDK (the
LDOs and DCDCs are always on).
A DT-only boot with this addition gives functional UART, reboot via
watchdog, RTC, ethernet and MMC (I added the CD GPIO for the MMC
although davinci_mmc doesn't call the OF facilities of mmc core).

the same platform data is passed to the voicecodec present on that

f7df9be067 ARM: DT updates for v4.7
These are all the updates to device tree files for 32-bit platforms,
 which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
 changesets, 450 files changed, 23340 insertions, 5216 deletions.
 
 The three platforms that are added with the "soc" branch are here as well,
 and we add some related machine files:
 
 - For Aspeed AST2400/AST2500, we get the evaluation platform and
   the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
 - For Oxnas 810SE, the Western Digital "My Book World Edition"
   is added as the only platform at the moment.
 - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
   are supported
 
 On the ARM Realview development platform, we now support all machines
 with device tree, previously only the board files were supported, which
 in turn will likely be removed soon.
 
 Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",

 "These are all the updates to device tree files for 32-bit platforms,
  which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
  changesets, 450 files changed, 23340 insertions, 5216 deletions.

  The three platforms that are added with the "soc" branch are here as
  well, and we add some related machine files:

   - For Aspeed AST2400/AST2500, we get the evaluation platform and the
     Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
   - For Oxnas 810SE, the Western Digital "My Book World Edition" is
     added as the only platform at the moment.
   - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7) are
     supported

  On the ARM Realview development platform, we now support all machines
  with device tree, previously only the board files were supported,
  which in turn will likely be removed soon.

  Qualcomm IPQ4019 is the second generation ARM based "Internet
  Processor", following the IPQ806x that is used in many high-end WiFi
  routers.  This one integrates two ath10k wifi radios that were
  previously on separate chips.

  Other boards that got added for existing chips are:

  Ti OMAP family:
     - Amazon Kindle Fire, first generation, tablet and ebook reader
     - OnRISC Baltos iR 2110 and 3220 embedded industrial PCs
     - TI AM5728 IDK, TI AM3359 ICE-V2, and TI DRA722 Rev C EVM

9896c7b57e ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount
 of changes in arch/arm for any of them is miniscule, as all the
 interesting code is in device driver subsystems (irqchip, clk, pinctrl,
 ...) these days. I'm listing them here, as the addition of the Kconfig
 statement is the main relevant milestone for a new platform. In each
 case, some drivers are are shared with existing platforms, while
 other drivers are added for v4.7 as well, or come in a later release.
 
 - The Aspeed platform is probably the most interesting one, this is
   what most whitebox servers use as their baseboard management
   controller. We get support for the very common ast2400 and ast2500
   SoCs. The OpenBMC project focuses on this chip, and the LWN
   article about their ELC 2016 presentation at
   https://lwn.net/Articles/683320/ triggered the submission, but the
   code comes from IBM's OpenPOWER team rather than the team at
   Facebook. There are still a lot more drivers that need to get added
   over time, and I hope both teams can work together on that.
 
 - OXNAS is an old platform for Network Attached Storage devices
   from Oxford Semiconductor. There are models with ARM10 (!) and
   ARM11MPCore cores, but for now, we only support the original ARM9
   based versions.
   The product lineup was subsequently part of PLX, Avago and now the
   new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
   has some more information.
 
 - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
   cores and is related to the existing Realview / Versatile Express
   lineup, but without MMU. We now support various NOMMU platforms,
   so adding a new one is fairly straightforward.
   http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
   has detailed information about the platform.
 
 Other noteworthy updates:
 
 - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux
   are now maintaining the platform. This is an older ARM9 based
   platform from NXP (not Freescale), but it remains in use in embedded
   markets.
 
 - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both
   32-bit and 64-bit ARM, and started contributing some patches.
 
 - As is often the case, work on the OMAP platforms makes up the bulk of
   the actual SoC code changes in arch/arm, but there isn't a lot of
   that either.

f2b1e0f638 ARM: SoC cleanups and fixes for v4.7
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.

04b9665b54 ARM: davinci: only use NVMEM when available
The davinci platform contains code that calls into the nvmem
subsystem, but that might be a loadable module, causing a
link error:

arch/arm/mach-davinci/built-in.o: In function `davinci_get_mac_addr':
:(.text+0x1088): undefined reference to `nvmem_device_read'
arch/arm/mach-davinci/built-in.o: In function `read_factory_config':
:(.text+0x214c): undefined reference to `nvmem_device_read'

Also, when NVMEM is completely disabled, the functions fail with
nonobvious error messages.

This ensures we only call the API functions when the code is actually
reachable from the board file, and otherwise prints a unique log
message.

3f2a09d57b ARM: davinci: da850: use clk->set_parent for async3
The da850 family of processors has an async3 clock domain that can be
muxed to either pll0_sysclk2 or pll1_sysclk2. Now that the davinci clocks
have a set_parent callback, we can use this to control the async3 mux
instead of a stand-alone function.

This adds a new async3_clk and sets the appropriate child clocks. The
default is use to pll1_sysclk2 since it is not affected by processor
frequency scaling.

6fc9ebbdeb ARM: davinci: Move clock init after ioremap.
Some clocks (such as the USB PHY clocks in DA8xx) will need to use iomem.
The davinci_common_init() function must be called before the ioremap, so
the clock init is now split out as separate function.
