Merge tag 'late-omap' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late OMAP changes from Olof Johansson:
"This branch contains changes for OMAP that came in late during the
release staging, close to when the merge window opened.
It contains, among other things:
- OMAP PM fixes and some patches for audio device integration
- OMAP clock fixes related to common clock conversion
- A set of patches cleaning up WFI entry and blocking.
- A set of fixes and IP block support for PM on TI AM33xx SoCs
(Beaglebone, etc)
- A set of smaller fixes and cleanups around AM33xx restart and
revision detection, as well as removal of some dead code
(CONFIG_32K_TIMER_HZ)"
