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

Pull arm SoC platform updates from Olof Johansson:
 "SoC updates, mostly refactorings and cleanups of old legacy platforms,
  but also a few more things:

  New SoC support this release:
   - NXP/Freescale i.MX7ULP (1x Cortex-A7, Cortex-M4, graphics, etc)
   - Allwinner F1C100, older platform with an ARM926-EJS (ARMv5) core

  Cleanups of various platforms:
   - OMAP1 ams-delta does some GPIO cleanups
   - Davinci removes of at24 platform data
   - Samsung cleans up old wakeup, PM debug and secondary core boot code
   - Renesas moves around config options and PM code to drivers/soc for
     sharing with 64-bit and more consistency
   - i.MX, Broadcom and SoCFPGA all have tweaks to lowlevel debug
     console setups
   - SoCFPGA adds explicit selection of ARM errata and removes some
     unused code

  This also contains a few patches that I had queued up as fixes for
  4.20 but didn't send in before the release"
