Merge tag 'omap-fixes-b-for-3.10-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.10/fixes
More OMAP hwmod and clock fixes for v3.10-rc. Fixes the AM33xx UART2. Also fixes some CCF-related breakage on OMAP36xx/37xx, affecting DSS at the very least. Basic test logs for this branch are here: http://www.pwsan.com/omap/testlogs/fixes_b_v3.10-rc/20130606093449/
