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

Pull ARM SoC platform changes from Olof Johansson:
 "New and updated SoC support.  Among the things new for this release
  are:

   - More support for the AM33xx platforms from TI
   - Tegra 124 support, and some updates to older tegra families as well
   - imx cleanups and updates across the board
   - A rename of Broadcom's Mobile platforms which were introduced as
     ARCH_BCM, and turned out to be too broad a name.  New name is
     ARCH_BCM_MOBILE.
   - A whole bunch of updates and fixes for integrator, making the
     platform code more modern and switches over to DT-only booting.
   - Support for two new Renesas shmobile chipsets.  Next up for them is
     more work on consolidation instead of introduction of new
     non-multiplatform SoCs, we're all looking forward to that!
   - Misc cleanups for older Samsung platforms, some Allwinner updates,
     etc"
