Merge tag 'omap-fixes-a-for-pre3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.7-rc1/fixes-hwmod-clock
Some OMAP fixes for the 3.7 merge window, fixing mismerges, branch integration issues, and bugs after the arm-soc merges. Basic test logs are available here: http://www.pwsan.com/omap/testlogs/devel_late_fixes_3.7/20121009084003/ N800 isn't booting; this is a problem present in the base commit and is due to serial driver breakage: http://www.spinics.net/lists/arm-kernel/msg196034.html
