Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann:
"Driver updates for ARM SoCs.
A handful of driver changes this time around. The larger changes are:
- Reset drivers for hi3660 and zx2967
- AHCI driver for Davinci, acked by Tejun and brought in here due to
platform dependencies
- Cleanups of atmel-ebi (External Bus Interface)
- Tweaks for Rockchip GRF (General Register File) usage (kitchensink
misc register range on the SoCs)
- PM domains changes for support of two new ZTE SoCs (zx296718 and
zx2967)"
