Merge tag 'omap-for-v4.4/fixes-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Merge "omap fixes against v4.4-rc4" from Tony Lindgren

Few fixes for omaps for v4.4-rc cycle:

- Fix clock source for ARM TWD and global timers on am437x

- Always select REGULATOR_FIXED_VOLTAGE for omap2+ instead of
  when MACH_OMAP3_PANDORA is selected

- Fix SPI DMA handles for dm816x as only some were mapped

- Fix up mbox cells for dm816x to make mailbox usable
