Merge tag 'omap-for-v4.3/fixes-rc5' of... 

Merge tag 'omap-for-v4.3/fixes-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "Fixes for omap against v4.3-rc5" from Tony Lindgren:

- Regulator fix for beagle-x15 to fix HDMI without a SD card being
  inserted

- GPMC fix for showing proper timings and to allow enabling debug
  options that somehow was unselectable earlier

- Add minimal documentation for new MMC1 dependency on
  REGULATOR_PBIAS as it may not be obvious for people with
  targeted .config files
