Merge tag 'for-v4.1-rc/omap-fixes-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.1/fixes
ARM: OMAP2+: first set of hwmod fixes for v4.1-rc
Fix a few AM43xx problems: add the VPFE hwmod data, which removes some
warnings; and fix the IP block hardreset implementation.
Basic build, boot, and PM test results are here:
http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.1-rc/20150508130543/
Note that I do not have an AM43xx board in the testbed, and thus
cannot test on that platform.
