Merge tag 'omap-fixes-non-critical-for-v3.6' of git://git.kernel.org/…

…pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical

From Tony Lindgren <tony@atomide.com>:

This branch contains fixes that were too intrusive or not
critical enough for the 3.5 -rc cycle. The biggest changes are
fixes for the am35xx clock and hwmod data, and the removal of dead
code for the 730 and 850 headers.
