Merge tag 'omap-for-v3.8/devel-prcm-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/pm2

From Tony Lindgren:

omap prcm changes via Paul Walmsley <paul@pwsan.com>:

Some miscellaneous OMAP hwmod changes for 3.8, along with a PRM
change needed for one of the hwmod patches to function.

Basic test logs for this branch on top of Tony's
omap-for-v3.8/clock branch at commit
558a0780b0a04862a678f7823215424b4e5501f9 are here:

http://www.pwsan.com/omap/testlogs/hwmod_devel_a_3.8/20121121161522/

However, omap-for-v3.8/clock at 558a0780 does not include some fixes
that are needed for a successful test.  With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:

http://www.pwsan.com/omap/testlogs/TEST_hwmod_devel_a_3.8/20121121162719/

which indicate that the series tests cleanly.
