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.
A slew of changes this release cycle. The reset driver tree, that we
merge through arm-soc for historical reasons, is also sizable this
time around.
Among the changes:
- clps711x: Treewide changes to compatible strings, merged here for simplicity.
- Qualcomm: SCM firmware driver cleanups, move to platform driver
- ux500: Major cleanups, removal of old mach-specific infrastructure.
- Atmel external bus memory driver
- Move of brcmstb platform to the rest of bcm
- PMC driver updates for tegra, various fixes and improvements
- Samsung platform driver updates to support 64-bit Exynos platforms
- Reset controller cleanups moving to devm_reset_controller_register() APIs
- Reset controller driver for Amlogic Meson
- Reset controller driver for Hisilicon hi6220
- ARM SCPI power domain support"
