Merge tag 'omap-fixes-a2-for-v3.8-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8-rc2/fixes
Some OMAP PRCM and sparse fixes against v3.8-rc1. A basic set of test logs are available here: http://www.pwsan.com/omap/testlogs/prcm_fixes_b_3.8-rc/20130102120724/ The 3730 Beagle XM here has an intermittent failure mounting SD root, but the suspicion right now is that this is due to a failing SD card, rather than any change introduced by these patches. This second version includes a few changes requested by Tony Lindgren.
