Merge tag 'for-v3.12/dra7xx' of...

Merge tag 'for-v3.12/dra7xx' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.12/soc

This series adds basic TI DRA7xx PRCM and hwmod support.

Basic test logs are available here:

http://www.pwsan.com/omap/testlogs/dra7xx_prcm_devel_v3.12/20130823050445/

Note that DRA7xx could not be tested locally, since I don't have a board.
