Linus Torvalds 6fa52ed33b 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.

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.
