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

Pull ARM SoC fixes from Olof Johansson:
 "I've been bad at collecting fixes this release cycle, so this is a
  fairly large batch that's been trickling in for a while.

  It's the usual mix, more or less.

  Some of the bigger things fixed:

   - Voltage fix for MMC on TI DRA7 that sometimes would overvoltage
     cards

   - Regression fixes for D_CAN on am355x

   - i.MX6SX cpuidle fix to deal with wakeup latency (dropped uart
     chars)

   - DT fixes for some DRA7 variants that don't share the superset of
     blocks on the chip

  plus the usual mix of stuff: minor build/warning fixes, Kconfig
  dependencies, and some DT fixlets"
