Merge tag 'omap-devel-am33xx-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
From Tony Lindgren: From Paul Walmsley <paul@pwsan.com>: AM33xx hwmod data and miscellaneous clock and hwmod fixes. AM33xx should now boot on mainline after this is applied, according to Vaibhav. (The shortlog makes no sense here since it contains mostly the dependent cleanups that are part of the preceding branches). Signed-off-by: Olof Johansson <olof@lixom.net>
