Merge tag 'tags/omap-for-v3.8/devel-prcm-signed' into omap-for-v3.8/cleanup-headers-prepare-multiplatform-v3
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.
