Linus Torvalds 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.

Simon Horman 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.
