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

Pull ARM SoC driver updates from Olof Johansson:
 "Driver updates for ARM SoCs:

  Reset subsystem, merged through arm-soc by tradition:
   - Make bool drivers explicitly non-modular
   - New support for i.MX7 and Arria10 reset controllers

  PATA driver for Palmchip BK371 (acked by Tejun)

  Power domain drivers for i.MX (GPC, GPCv2)
   - Moved out of mach-imx for GPC
   - Bunch of tweaks, fixes, etc

  PMC support for Tegra186

  SoC detection support for Renesas RZ/G1H and RZ/G1N

  Move Tegra flow controller driver from mach directory to drivers/soc
   - (Power management / CPU power driver)

  Misc smaller tweaks for other platforms"
