Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Kevin Hilman:
"Another round of fixes from arm-soc land, which are mostly DT fixes
for:
- OMAP: handful of DT fixes devices on newly supported hardware
- davinci: fix 2nd EDMA channel
- ux500: extend previous pinctrl fix to another board
- at91: clock registration fixes, compatibility string precision
And one more fix for event cleanup in drivers/bus/arm-ccn"
