Merge tag 'for-v3.17-rc/omap-dra72x-d74x-support-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes
Pull "ARM: OMAP2+: DRA72x/DRA74x basic support" from Tony Lindgren:
Add basic subarchitecture support for the DRA72x and DRA74x. These
are OMAP2+ derivative SoCs. This should be low-risk to existing OMAP
platforms.
Basic build, boot, and PM test logs are available here:
