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:
"Misc driver updates for platforms, many of them power related.
- Rockchip adds power domain support for rk3066 and rk3188
- Amlogic adds a power measurement driver
- Allwinner adds SRAM support for three platforms (F1C100, H5, A64
C1)
- Wakeup and ti-sysc (platform bus) fixes for OMAP/DRA7
- Broadcom fixes suspend/resume with Thumb2 kernels, and improves
stability of a handful of firmware/platform interfaces
- PXA completes their conversion to dmaengine framework
- Renesas does a bunch of PM cleanups across many platforms
- Tegra adds support for suspend/resume on T186/T194, which includes
some driver cleanups and addition of wake events
- Tegra also adds a driver for memory controller (EMC) on Tegra2
- i.MX tweaks power domain bindings, and adds support for i.MX8MQ in
GPC
- Atmel adds identifiers and LPDDR2 support for a new SoC, SAM9X60
and misc cleanups across several platforms"
