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:
"Some of the larger changes this merge window:
- Removal of drivers for Exynos5440, a Samsung SoC that never saw
widespread use.
- Uniphier support for USB3 and SPI reset handling
- Syste control and SRAM drivers and bindings for Allwinner platforms
- Qualcomm AOSS (Always-on subsystem) reset controller drivers
- Raspberry Pi hwmon driver for voltage
- Mediatek pwrap (pmic) support for MT6797 SoC"
