688e6a6df8 ARM: shmobile: bockw: add R-Car sound support (PIO)
This patch enables R-Car sound,
AK4643 (CN19) and AK4554 (CN20/CN21) codec chip
on Bock-W.

But, it supports PIO transfer only at this point.
User can check sound settings (Dip-switch/PFC etc)
via this patch, but will get under/over flow error
when playback/capture.
Because PIO transfer via SSI will be interrupted
"sampling rate" times per 1 second.

DMA transfer will be supported when HPB-DMAC was
enabled on r8a7778.

You will notice strange ALSA sound card HW
numbering on Bock-W board.
This came from AK4554 strange format on playback/capture.
The format on playback/capture is same on "normal" codec chip,
but AK4554 was different.
Because of that, AK4554 playback/capture are
registered as a different sound card.

0d0771ab2b ARM: shmobile: Initial r8a7791 SoC support
Add initial support for the r8a7791 SoC including:
 - Single Cortex-A15 CPU Core
 - GIC

No static virtual mappings are used, all the components
make use of ioremap(). DT_MACHINE_START is still wrapped
in CONFIG_USE_OF to match other mach-shmobile code.

fa91515cbf ARM: Renesas SoC cleanup, refactoring and more SMP support
Lots of cleanup and refactoring and some SMP additions for Renesas
 platforms.  Due to some inter-dependencies with other arm-soc
 branches, this Renesas stuff was separated out for sending after the
 other branches were merged.
 
 Highlights:
 - remove unused board support and cleanup of unused headers
 - refactoring of init and device registration
 - simplify IRQ initialization
 
 Conflicts: Too many. Most of these are because Simon chose to send
 some board updates through the V4L tree that ends up colliding with
 the main platform changes. We'll work with him on sorting out his
 workflow:
 
 - arch/arm/boot/dts/r8a7740.dtsi:
   - Add/add conflict in a devicetree file (keep both)
 
 - arch/arm/mach-shmobile/Makefile:
   - Splitting out of clock files collides with intc move to DT.
     Keep HEAD version but remove intc-* files for R8A7740 and R8A7779.
 
 - arch/arm/mach-shmobile/board-bockw.c:
   - Keep HEAD but remove i2c, hspi and mmc device init calls
 
 - arch/arm/mach-shmobile/board-marzen.c
   - Remove mach/hardware.h include and r8a7779_add_usb_phy_device() call,
     everything else stays.
 
 - arch/arm/mach-shmobile/include/mach/r8a7778.h:
   - From HEAD, Keep camera-rcar.h include and r8a7778_add_vin_device()
   - From branch, keep everything
 
 - arch/arm/mach-shmobile/include/mach/r8a7779.h:
   - From HEAD, Keep only camera-rcar.h include and r8a7779_add_vin_device()
 
 - arch/arm/mach-shmobile/setup-r8a7778.c
   - Keep HEAD, but drop the MMC section (struct resource + add_mmc_device())
   - take the new function name from our side (r8a7778_add_dt_devices())
 
 - arch/arm/mach-shmobile/setup-r8a7779.c
   - Keep HEAD, but drop r8a7779_add_usb_phy_device()
 
 I've also pushed a test-merge2 branch where you can see how I resolved
 them.

44598f98b9 ARM: SoC board updates for 3.12
Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
 but most of this is around legacy code and board support. We've found that
 platform maintainers have a hard time separating all of these out and might
 move towards fewer branches for next release.
 
 - Removal of a number of Marvell Kirkwood board files, since contents
   is now common and mostly configured via DT.
 - Device-tree updates for Marvell Dove, including irqchip and clocksource
   setup.
 - Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
 - New backlight drivers for backlights used on Renesas shmobile platforms.
 - Removal of Renesas leds driver.
 - Shuffling of some of the new Broadcom platforms to give room for others in
   the same mach directory. More in 2.13.

b4b50fd78b ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
 and SoC-level drivers. Since there's sometimes a dependency on device-tree
 changes, there's also a fair amount of those in this branch.
 
 Pieces worth mentioning are:
 
 - Mbus driver for Marvell platforms, allowing kernel configuration
   and resource allocation of on-chip peripherals.
 - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
 - Preparation of MSI support for Marvell platforms.
 - Addition of new PCI-e host controller driver for Tegra platforms
 - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
   platforms in the device tree sources and header files.
 - Various suspend/PM updates for Tegra, including LP1 support.
 - Versatile Express support for MCPM, part of big little support.
 - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
 - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
 
 The code that touches other architectures are patches moving
 MSI arch-specific functions over to weak symbols and removal of
 ARCH_SUPPORTS_MSI, acked by PCI maintainers.

This is sufficient to allow boot of the Lager board with
a console without boards-lager.c compiled into the kernel.
This is an example of a minimal but still useful initialisation
of the board using DT as much as possible.

As such it is the same as the boot of Lager that can be achieved
without a board file. The intention of adding this file
is to facilitate further work to allow board specific devices to be
initialised via DT.

03393e8fe6 ARM: shmobile: KZM9D DT reference implementation
Add a DT reference implementation for the KZM9D board.

Only DT devices are used in this case. UART, STI, GPIO
and SMP / GIC are all provided by emev2.dtsi.

There is still a board specific C file used for enabling
legacy SH clocks. This file will be removed after we have
moved over to common clocks.

fb2af0020a Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "This contains the usual updates from other people (listed below) and
  the usual random muddle of miscellaneous ARM updates which cover some
  low priority bug fixes and performance improvements.

  I've started to put the pull request wording into the merge commits,
  which are:

   - NoMMU stuff:

     This includes the following series sent earlier to the list:
      - nommu-fixes
      - R7 Support
      - MPU support

     I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
     were discussing today until we've reached a conclusion/that's had
     some more review.

     This is rebased (and re-tested) on your devel-stable branch because
     otherwise there were going to be conflicts with Uwe's V7M work now
     that you've merged that.  I've included the fix for limiting MPU to
     CPU_V7.

   - Huge page support

     These changes bring both HugeTLB support and Transparent HugePage
     (THP) support to ARM.  Only long descriptors (LPAE) are supported
     in this series.

     The code has been tested on an Arndale board (Exynos 5250).

   - LPAE updates

     Please pull these miscellaneous LPAE fixes I've been collecting for
     a while now for 3.11.  They've been tested and reviewed by quite a
     few people, and most of the patches are pretty trivial.  -- Will Deacon.

   - arch_timer cleanups

     Please pull these arch_timer cleanups I've been holding onto for a
     while.  They're the same as my last posting, but have been rebased
     to v3.10-rc3.

   - mpidr linearisation (multiprocessor id register - identifies which
     CPU number we are in the system)

     This patch series that implements MPIDR linearization through a
     simple hashing algorithm and updates current cpu_{suspend}/{resume}
     code to use the newly created hash structures to retrieve context
     pointers.  It represents a stepping stone for the implementation of
     power management code on forthcoming multi-cluster ARM systems.

     It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
     OMAP4 and Tegra, with processors hitting low-power states requiring
     warm-boot resume through the cpu_resume code path"

ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

fb521a0da1 arm: fix up ARM_ARCH_TIMER selects
In 8a4da6e: "arm: arch_timer: move core to drivers/clocksource", the
selection of ARM_ARCH_TIMER was indirected via HAVE_ARM_ARCH_TIMER,
though mach-exynos's selection of ARM_ARCH_TIMER was missed, and since
then mach-shmobile, mach-tegra, and mach-virt have begun selecting
ARM_ARCH_TIMER. This can lead to architected timer support erroneously
appearing to not be selected in menuconfig.

This patch fixes up the Kconfigs for those platforms to select
HAVE_ARM_ARCH_TIMER.

IRQ signals. The IRQC controller is tied to SPIs of
the GIC. On r8a7790 the external IRQ pins routing is
handled by the PFC which is excluded from this patch.

Both platform devices and DT devices are added in this
patch. The platform device versions are used to provide
a static interrupt map configuration for board code
written in C.

Add initial support for the r8a7790 SoC including:
 - Single Cortex-A15 CPU Core
 - GIC

No static virtual mappings are used, all the components
make use of ioremap(). DT_MACHINE_START is still wrapped
in CONFIG_USE_OF to match other mach-shmobile code.

0b7d782022 ARM: shmobile: r8a7740: Migrate from INTC to GIC
With the added capabilty of the intc_irqpin driver to handle shared
external IRQs, all prerequisites are fulfilled and we are ready to
migrate completely to GIC. This includes the following steps:

- Kconfig:	select ARM_GIC and RENESAS_INTC_IRQPIN
- intc-r8a7740: Throw out all legacy INTC code and init the GIC. We need
  		to mask out all shared IRQs as it is needed by the
		shared intc_irqpin driver.
- setup-r8a7740: Add 4 irqpin devices to handle external IRQs and update
		all IRQ numbers to point to the GIC SPI.
- board-armadillo: Update all IRQ numbers to point to the GIC SPI.
- pfc-r8a7740:	Update all IRQ numbers of the GPIOs to point to the GIC
		SPI.

have to depend on their respective "legacy" configurations, doing device

b8b82b2983 ARM: shmobile: kzm9g: Reference DT implementation
Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.

Some notes:

* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
  - MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
  thus external devices may not be used. In particular,
  the SMSC ethernet device may not be used and thus
  NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
  which are needed for a working board:
  - SCIF (Serial)
  - CMT (Clock)
  - PFC (GPIO)

To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.

Includes fix by Thierry Reding to no longer use gic_handle_irq()

Includes fixes by Guennadi Liakhovetski for recent pinmux changes.

8e56e6d5bf ARM: shmobile: INTC External IRQ pin driver on r8a7779
Update the r8a7779 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ3.

The r8a7779 SoC can like older SH SoCs configure
to use the IRQ0 -> IRQ3 signals as individual
interrupts or a combined IRL mode.

Without this patch the r8a7779 SoC code does
not fully support external IRQ pins in individual
IRQ mode. The r8a7779 PFC code does not yet have
gpio_to_irq() support so no need to update such
code.

At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.
