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

Pull ARM SoC fixes from Olof Johansson:
 "A smaller batch of fixes, nothing that stands out as risky or scary.

  Mostly DTS tweaks for a few issues:

   - GPU fixlets for Meson

   - CPU idle fix for LS1028A

   - PWM interrupt fixes for i.MX6UL

  Also, enable a driver (FSL_EDMA) on arm64 defconfig, and a warning and
  two MAINTAINER tweaks"
