Merge tag 'omap-for-v3.10/fixes-v3.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
Pulling in a set of fixes from Tony Lindgren to resolve conflicts with later
cleanup branch:
A set of small fixes for omaps for the -rc cycle:
- am7303 iva2 reset PM regression fix
- am33xx uart2 dma channel fix
- am33xx gpmc properties fix
- omap44xx rtc wake-up mux fix for nirq pins
- omap36xx clock divider restore fix
There's also one tiny non-critical .dts fix for omap5
timer pwm properties.
