Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Olof Johansson:
"New or improved SoC support:
- add support for Atmel's SAMA5D2 SoC
- add support for Freescale i.MX6UL
- improved support for TI's DM814x platform
- misc fixes and improvements for RockChip platforms
- Marvell MVEBU suspend/resume support
A few driver changes that ideally would belong in the drivers branch
are also here (acked by appropriate maintainers):
- power key input driver for Freescale platforms (svns)
- RTC driver updates for Freescale platforms (svns/mxc)
- clk fixes for TI DM814/816X
+ a bunch of other changes for various platforms"
