Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Arnd Bergmann:
 "A few patches have come up since the merge window.  The largest one is
  a rewrite of the PXA lubbock/mainstone IRQ handling.  This was already
  broken in 2011 by a change to the GPIO code and only noticed now.

  The other changes contained here are:

  MAINTAINERS file updates:

   - Ray Jui and Scott Branden are now co-maintainers for some of the
     mach-bcm chips, while Christian Daudt and Marc Carino have stepped
     down.

   - Andrew Victor is no longer maintaining at91.  Instead, Alexandre
     Belloni now becomes an official maintainer, after having done a
     bulk of the work for a while.

   - Baruch Siach, who added the mach-digicolor platform in 4.1 is now
     listed as maintainer

   - The git URL for mach-socfpga has changed

  Bug fixes:

   - Three bug fixes for new rockchip rk3288 code

   - A regression fix to make SD card support work on certain ux500
     boards

   - multiple smaller dts fixes for imx, omap, mvebu, and shmobile

   - a regression fiix for omap3 power consumption

   - a fix for regression in the ARM CCI bus driver

  Configuration changes:

   - more imx platforms are now enabled in multi_v7_defconfig"
