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: http://www.pwsan.com/omap/testlogs/hwmod-a-early-v3.17-rc/20140827194314/ * tag 'for-v3.17-rc/omap-dra72x-d74x-support-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending: ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists ARM: DRA7: Add support for soc_is_dra74x() and soc_is_dra72x() variants Signed-off-by: Olof Johansson <olof@lixom.net>
