5ad945ea58 ARM: at91: cpuidle: Convert to platform driver
Using the platform driver model is a good way to separate the cpuidle specific
code from the low level pm code. It allows to remove the dependency between
these two components.

The platform_device is located in the pm code and a 'set' function has been
added to set the standby function from the AT91_SOC_START initialization
function. Each SoC with a cpuidle driver will set the standby function in the
platform_data field at init time. Then pm code will register the cpuidle
platform device.

The cpuidle driver will register the platform_driver and use the device's
platform_data as a standby callback in the idle path.

The at91_pm_enter function contains a { if then else } based on cpu_is_xx
similar to what was in cpuidle. This is considered dangerous when adding a new
SoC. Like the cpuidle driver, a standby ops is defined and assigned when the
SoC init function specifies what is its standby function and reused in the
at91_pm_enter's 'case' block.

f123248e17 ARM: at91: remove init_machine() as default is suitable
Since 883a106b08 (ARM: default
machine descriptor for multiplatform) we can remove the SoC-specific
callback init_machine() to use the default code.
This cleans up the code and reduces the number of lines.

bd737fea4e ARM: at91: sam9g45: shutdown ddr1 too when rebooting
Like we are doing on DDR0 we need to cleanly shutdown DDR1 if it is
used before rebooting.
If DDR1 is not initialized, we check it and avoid dereferencing its address.
Even by adding two more instructions, we are able to complete the procedure
within a single cache line.

 "This branch contains mostly additions and changes to platform
  enablement and SoC-level drivers.  Since there's sometimes a

   - 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

The following commit:

commit 7e348b9012
Author: Robert Lee <rob.lee@linaro.org>
Date:   Tue Mar 20 15:22:43 2012 -0500

    ARM: at91: Consolidate time keeping and irq enable

    Enable core cpuidle timekeeping and irq enabling and remove that
    handling from this code.

introduced an additional zero to the state1 (suspend) target residency.

With a periodic tick, the cpu never enters the state1 with both 10000 and
100000.

With a tickless system, it enters to state1 much more often with the
initial value, roughly x7 more.

Fix it by setting the value to 10ms again.

546c830c90 ARM: at91: fix at91_extern_irq usage for non-dt boards
Since 4b68520dc0ec96153bc0d87bca5ffba508edfcf
ARM: at91: add AIC5 support

we allocate the at91_extern_irq.

This patch makes it static and stores the non-dt extern irq in the soc
structure. It is then possible to use a at91_get_extern_irq() function
to get the value for outside of the irq driver. It is useful for passing
its value to at91_aic_init().

Pull ARM SoC late cleanups from Arnd Bergmann:
 "These are cleanups and smaller changes that either depend on earlier

  normally try to get all cleanups early, so these are the exceptions:

   - A follow-up on the clocksource reworks, hopefully the last time we
     need to merge clocksource subsystem changes through arm-soc.

     A first set of patches was part of the original 3.10 arm-soc
     cleanup series because of interdependencies with timer drivers now
     moved out of arch/arm.

   - Migrating the SPEAr13xx platform away from using auxdata for DMA
     channel descriptions towards using information in device tree,
     based on the earlier SPEAr multiplatform series

   - A few follow-ups on the Atmel SAMA5 support and other changes for
     Atmel at91 based on the larger at91 reworks.

   - Moving the armada irqchip implementation to drivers/irqchip

   - Several OMAP cleanups following up on the larger series already
     merged in 3.10."

6fa52ed33b Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver changes from Olof Johansson:
 "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."
