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, these contain various things that touch
the drivers/ directory but got merged through arm-soc for practical
reasons:
- Rockchip rk3368 gains power domain support
- Small updates for the ARM spmi driver
- The Atmel PMC driver saw a larger rework, touching both
arch/arm/mach-at91 and drivers/clk/at91
- All reset controller driver changes alway get merged through
arm-soc, though this time the largest change is the addition of a
MIPS pistachio reset driver
- One bugfix for the NXP (formerly Freescale) i.MX weim bus driver"
