Merge tag 'omap-for-v4.7/soc-signed' of git://git.kernel.org/pub/scm/…

…linux/kernel/git/tmlind/linux-omap into next/soc

Merge "SoC related changes for omaps for v4.7 merge window" from Tony Lindgren:

- Remove now unnecessary multi vs single SoC compile time optimizations
  as we are now using multiarch

- Configure dra7 powerdomains

- Clarify why omap-wakeupgen does not need to handle FROZEN transitions

- Add dra7 module configuration for MaASP, PWMSS and timer 12

- Add RTC module configuration unlock and lock functions

- Fix hwmod idle state sanity check sequence
