This is the bulk of pin control changes for the v4.3 development
cycle
Core changes:
- It is possible configure groups in debugfs.
- Consolidation of chained IRQ handler install/remove replacing
all call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a
combined call to irq_set_chained_handler_and_data(). This
series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which
is way cleaner.
- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs
from IRQ numbers. The goal is to get rid of the irq number
from the handlers in the IRQ flow which is nice.
Driver feature enhancements:
- Power management support for the SiRF SoC Atlas 7.
- Power down support for the Qualcomm driver.
- Intel Cherryview and Baytrail: switch drivers to use raw
spinlocks in IRQ handlers to play nice with the realtime
patch set.
- Rework and new modes handling for Qualcomm SPMI-MPP.
- Pinconf power source config for SH PFC.
New drivers and subdrivers:
- A new driver for Conexant Digicolor CX92755.
- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
- Reverse-egineered the S/PDIF settings for the Allwinner
sun4i driver.
- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
- A new Freescale i.mx6ul subdriver.
Cleanup:
- Remove platform data support in a number of SH PFC
subdrivers.

Like with GPIO it's a lot of stuff. If my subsystems are any sign of

nvmem: Add a simple NVMEM framework for nvmem providers
This patch adds just providers part of the framework just to enable easy review. Up until now, NVMEM drivers like eeprom were stored in drivers/misc, where they all had to duplicate pretty much the same code to register a sysfs file, allow in-kernel users to access the content of the devices they were driving, etc. This was also a problem as far as other in-kernel users were involved, since the solutions used were pretty much different from on driver to another, there was a rather big abstraction leak. This introduction of this framework aims at solving this. It also introduces DT representation for consumer devices to go get the data they require (MAC Addresses, SoC/Revision ID, part numbers, and so on) from the nvmems. Having regmap interface to this framework would give much better abstraction for nvmems on different buses.

The libnvdimm sub-system introduces, in addition to the libnvdimm-core,
4 drivers / enabling modules:
NFIT:
Instantiates an "nvdimm bus" with the core and registers memory devices
(NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface
table). After registering NVDIMMs the NFIT driver then registers
"region" devices. A libnvdimm-region defines an access mode and the
boundaries of persistent memory media. A region may span multiple
NVDIMMs that are interleaved by the hardware memory controller. In
turn, a libnvdimm-region can be carved into a "namespace" device and
bound to the PMEM or BLK driver which will attach a Linux block device
(disk) interface to the memory.
PMEM:
Initially merged in v4.1 this driver for contiguous spans of persistent
memory address ranges is re-worked to drive PMEM-namespaces emitted by
the libnvdimm-core. In this update the PMEM driver, on x86, gains the
ability to assert that writes to persistent memory have been flushed all
the way through the caches and buffers in the platform to persistent
media. See memcpy_to_pmem() and wmb_pmem().
BLK:
This new driver enables access to persistent memory media through "Block
Data Windows" as defined by the NFIT. The primary difference of this
driver to PMEM is that only a small window of persistent memory is
mapped into system address space at any given point in time. Per-NVDIMM
windows are reprogrammed at run time, per-I/O, to access different
portions of the media. BLK-mode, by definition, does not support DAX.
BTT:
This is a library, optionally consumed by either PMEM or BLK, that
converts a byte-accessible namespace into a disk with atomic sector
update semantics (prevents sector tearing on crash or power loss). The
sinister aspect of sector tearing is that most applications do not know
they have a atomic sector dependency. At least today's disk's rarely
ever tear sectors and if they do one almost certainly gets a CRC error
on access. NVDIMMs will always tear and always silently. Until an
application is audited to be robust in the presence of sector-tearing
the usage of BTT is recommended.

A struct nvdimm_bus is the anchor device for registering nvdimm resources and interfaces, for example, a character control device, nvdimm devices, and I/O region devices. The ACPI NFIT (NVDIMM Firmware Interface Table) is one possible platform description for such non-volatile memory resources in a system. The nfit.ko driver attaches to the "ACPI0012" device that indicates the presence of the NFIT and parses the table to register a struct nvdimm_bus instance.

drivers: Move iommu/ before gpu/ in Makefile
AMD GPU devices are dependent on AMD IOMMU controller functionality to allow the GPU to access a process's virtual memory address space, without the need for pinning the memory. This patch changes the order in the drivers makefile, so iommu/ subsystem is linked before gpu/ subsystem. That way, if the gpu and iommu drivers are compiled inside the kernel image (not as modules), the correct order of device loading is still maintained (iommu module is loaded before gpu module).

Staging patches for 3.19-rc1
Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

coresight: add CoreSight core layer framework
CoreSight components are compliant with the ARM CoreSight architecture specification and can be connected in various topologies to suit a particular SoC tracing needs. These trace components can generally be classified as sources, links and sinks. Trace data produced by one or more sources flows through the intermediate links connecting the source to the currently selected sink. The CoreSight framework provides an interface for the CoreSight trace drivers to register themselves with. It's intended to build up a topological view of the CoreSight components and configure the correct serie of components on user input via sysfs. For eg., when enabling a source, the framework builds up a path consisting of all the components connecting the source to the currently selected sink(s) and enables all of them. The framework also supports switching between available sinks and provides status information to user space applications through the debugfs interface.

staging: android: binder: move to the "real" part of the kernel
The Android binder code has been "stable" for many years now. No matter what comes in the future, we are going to have to support this API, so might as well move it to the "real" part of the kernel as there's no real work that needs to be done to the existing code.

ARM: SoC driver changes
SoC-near driver changes that we're merging through our tree. Mostly because they depend on other changes we have staged, but in some cases because the driver maintainers preferred that we did it this way. This contains a largeish cleanup series of the omap_l3_noc bus driver, cpuidle rework for Exynos, some reset driver conversions and a long branch of TI EDMA fixes and cleanups, with more to come next release. The TI EDMA cleanups is a shared branch with the dmaengine tree, with a handful of Davinci-specific fixes on top. After discussion at last year's KS (and some more on the mailing lists), we are here adding a drivers/soc directory. The purpose of this is to keep per-vendor shared code that's needed by different drivers but that doesn't fit into the MFD (nor drivers/platform) model.

drivers: sh: compile drivers/sh/pm_runtime.c if ARCH_SHMOBILE_MULTI
If the kernel is built to support multi-ARM configuration with shmobile support built in, then drivers/sh is not built. This contains the PM runtime code in drivers/sh/pm_runtime.c, which implicitly enables the module clocks for all devices, and thus is quite essential. Without this, the state of clocks depends on implicit reset state, or on the bootloader. If ARCH_SHMOBILE_MULTI then build the drivers/sh directory, but ensure that bits that may conflict (drivers/sh/clk if the common clock framework is enabled) or are not used (drivers/sh/intc), are not built. Also, only enable the PM runtime code when actually running on a shmobile SoCs that needs it. ARCH_SHMOBILE_MULTI was added a while ago by commit |

video: move fbdev to drivers/video/fbdev
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY
SH-Mobile platforms are transitioning from non-multiplatform to multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has been created to group all multiplatform-enabled SH-Mobile SoCs. The existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't been converted yet. This arrangement works fine for the arch/ code, but lots of drivers needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on ARCH_SHMOBILE only. In order to avoid changing them, rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean ARCH_SHMOBILE configuration symbol that is selected by both ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

drivers: phy: add generic PHY framework
The PHY framework provides a set of APIs for the PHY drivers to create/destroy a PHY and APIs for the PHY users to obtain a reference to the PHY with or without using phandle. For dt-boot, the PHY drivers should also register *PHY provider* with the framework. PHY drivers should create the PHY by passing id and ops like init, exit, power_on and power_off. This framework is also pm runtime enabled. The documentation for the generic PHY framework is added in Documentation/phy.txt and the documentation for dt binding can be found at Documentation/devicetree/bindings/phy/phy-bindings.txt Cc: Tomasz Figa <t.figa@samsung.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Acked-by: Felipe Balbi <balbi@ti.com> Tested-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

For the 3.11 merge we only have one new MFD driver for the Kontron PLD.
But we also have: - Support for the TPS659038 PMIC from the palmas driver. - Intel's Coleto Creek and Avoton SoCs support from the lpc_ich driver. - RTL8411B support from the rtsx driver. - More DT support for the Arizona, max8998, twl4030-power and the ti_am335x_tsadc drivers. - The SSBI driver move under MFD. - A conversion to the devm_* API for most of the MFD drivers. - The twl4030-power got split from twl-core into its own module. - A major ti_am335x_adc cleanup, leading to a proper DT support. - Our regular arizona and wm* updates and cleanups from the Wolfson folks. - A better error handling and initialization, and a regulator subdevice addition for the 88pm80x driver. - A bulk platform_set_drvdata() call removal that's no longer need since commit |

mfd: Move ssbi driver into drivers/mfd
There is no reason for ssbi to have its own top-level driver directory when the only users of this interface are all MFD drivers. The only mainline driver using it at the moment (PM8921) is marked broken and in fact does not compile. I have verified that fixing the trivial build breakage in pm8921 links in the new ssbi code just fine, but that can be a separate patch.

ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem
specific interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into
platform specific interface, or to get called from platform specific
code, as long as all information about the hardware is provided
through a device tree.
Most of the drivers we touch this time are for clocksource. Since
now most of them are part of drivers/clocksource, I expect that we
won't have to touch these again from arm-soc and can let the
clocksource maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the
merge conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface
for taking devices on the SoC out of reset or back into reset.
Patches to use this interface on i.MX follow later in this merge
window, and we are going to have other platforms (at least tegra
and sirf) get converted in 3.11. This will let us get rid of
platform specific callbacks in a number of platform independent
device drivers.

add single-wire serial bus interface (SSBI) driver
SSBI is the Qualcomm single-wire serial bus interface used to connect the MSM devices to the PMIC and other devices. Since SSBI only supports a single slave, the driver gets the name of the slave device passed in from the board file through the master device's platform data. SSBI registers pretty early (postcore), so that the PMIC can come up before the board init. This is useful if the board init requires the use of gpios that are connected through the PMIC. Based on a patch by Dima Zavin <dima@android.com> that can be found at: http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=eb060bac4 This patch adds PMIC Arbiter support for the MSM8660. The PMIC Arbiter is a hardware wrapper around the SSBI 2.0 controller that is designed to overcome concurrency issues and security limitations. A controller_type field is added to the platform data to specify the type of the SSBI controller (1.0, 2.0, or PMIC Arbiter).

usual bunch of bug fixes, minor updates, embedded device tree updates
and new boards:
- Hand tuned asm implementation of SHA1 (by Paulus & Michael
Ellerman)
- Support for Doorbell interrupts on Power8 (kind of fast
thread-thread IPIs) by Ian Munsie
- Long overdue cleanup of the way we handle relocation of our open
firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard
- Support for saving/restoring & context switching the PPR (Processor
Priority Register) on server processors that support it. This
allows the kernel to preserve thread priorities established by
userspace. By Haren Myneni.
- DAWR (new watchpoint facility) support on Power8 by Michael Neuling
- Ability to change the DSCR (Data Stream Control Register) which
controls cache prefetching on a running process via ptrace by
Alexey Kardashevskiy
- Support for context switching the TAR register on Power8 (new
branch target register meant to be used by some new specific
userspace perf event interrupt facility which is yet to be enabled)
by Ian Munsie.
- Improve preservation of the CFAR register (which captures the
origin of a branch) on various exception conditions by Paulus.
- Move the Bestcomm DMA driver from arch powerpc to drivers/dma where
it belongs by Philippe De Muyter
- Support for Transactional Memory on Power8 by Michael Neuling

PCI-Express Non-Transparent Bridge Support
A PCI-Express non-transparent bridge (NTB) is a point-to-point PCIe bus connecting 2 systems, providing electrical isolation between the two subsystems. A non-transparent bridge is functionally similar to a transparent bridge except that both sides of the bridge have their own independent address domains. The host on one side of the bridge will not have the visibility of the complete memory or I/O space on the other side of the bridge. To communicate across the non-transparent bridge, each NTB endpoint has one (or more) apertures exposed to the local system. Writes to these apertures are mirrored to memory on the remote system. Communications can also occur through the use of doorbell registers that initiate interrupts to the alternate domain, and scratch-pad registers accessible from both sides. The NTB device driver is needed to configure these memory windows, doorbell, and scratch-pad registers as well as use them in such a way as they can be turned into a viable communication channel to the remote system. ntb_hw.[ch] determines the usage model (NTB to NTB or NTB to Root Port) and abstracts away the underlying hardware to provide access and a common interface to the doorbell registers, scratch pads, and memory windows. These hardware interfaces are exported so that other, non-mainlined kernel drivers can access these. ntb_transport.[ch] also uses the exported interfaces in ntb_hw.[ch] to setup a communication channel(s) and provide a reliable way of transferring data from one side to the other, which it then exports so that "client" drivers can access them. These client drivers are used to provide a standard kernel interface (i.e., Ethernet device) to NTB, such that Linux can transfer data from one system to the other in a standard way.

powerpc, dma: move bestcomm driver from arch/powerpc/sysdev to drivers/dma
The bestcomm dma hardware, and some of its users like the FEC ethernet component, is used in different FreeScale parts, including non-powerpc parts like the ColdFire MCF547x & MCF548x families. Don't keep the driver hidden in arch/powerpc where it is inaccessible for other arches. .c files are moved to drivers/dma/bestcomm, while .h files are moved to include/linux/fsl/bestcomm. Makefiles, Kconfigs and #include directives are updated for the new file locations. Tested by recompiling for MPC5200 with all bestcomm users enabled.

Staging: ipack: move out of staging
The ipack subsystem is cleaned up enough to now move out of the staging tree, and into drivers/ipack. Cc: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Cc: Jens Taprogge <jens.taprogge@taprogge.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

IPMI: Change link order
IPMI must be initialised before ACPI in order to ensure that any IPMI services are available before ACPI driver initialisation attempts to use any IPMI operation regions.
