 "These are changes that arrived a little late before the merge window
  or that have multiple dependencies on previous branches so they did
  not fit into one of the earlier ones.  There are 10 branches merged
  here, a total of 39 non-merge commits.  Contents are a mixed bag for
  the above reasons:

   * Two new SoC platforms: ST microelectronics stixxxx and the TI
     'Nspire' graphing calculator.  These should have been in the 'soc'
     branch but were a little late
   * Support for the Exynos 5420 variant in mach-exynos, which is based
     on the other exynos branches to avoid conflicts.
   * Various small changes for sh-mobile, ux500 and davinci
   * Common clk support for MSM"

pinctrl: samsung: Add support for SoC-specific suspend/resume callbacks

device to account for this.

pinctrl: samsung: fix suspend/resume functionality

2013-05-27T13:37:08+00:00

The GPIO states need to be restored after s2r and this is not currently
supported in the pinctrl driver. This patch saves the gpio states before
suspend and restores them after resume.

Saving and restoring is done very early using syscore_ops and must
happen before pins are released from their powerdown state.

rewritten by Doug Anderson .

pinctrl: Add pinctrl-s3c24xx driver

2013-05-20T15:56:13+00:00

The s3c24xx pins follow a similar pattern as the other Samsung SoCs and
can therefore reuse the already introduced infrastructure.

The s3c24xx SoCs have one design oddity in that the first 4 external
interrupts do not reside in the eint pending register but in the main
interrupt controller instead. We solve this by forwarding the external
interrupt from the main controller into the irq domain of the pin bank.
The masking/acking of these interrupts is handled in the same way.

Furthermore the S3C2412/2413 SoCs contain another oddity in that they
keep the same 4 eints in the main interrupt controller and eintpend
register and requiring ack operations to happen in both. This is solved
by using different compatible properties for the wakeup eint node which
set a property accordingly.

2013-05-04T19:31:18+00:00

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."
