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

Pull ARM SoC fixes from Arnd Bergmann:
 "There are three more fixes for this week:

   - The Windows-on-ARM laptops require a workaround to prevent crashing
     at boot from ACPI

   - The Renesas 'draak' board needs one bugfix for the backlight
     regulator

   - Also for Renesas, the 'hihope' board accidentally had its eMMC
     turned off in the 5.3 merge window"
