Merge tag 'omap-devel-b-c-2-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into devel-late
OMAP patches intended for the 3.7 merge window: - Runtime PM conversions for the GPMC and RNG IP blocks - Preparation patches for the OMAP common clock framework conversion - clkdev alias additions required by other drivers - Performance Monitoring Unit (PMU) support for OMAP2, 3, and non-4430 OMAP4 - OMAP hwmod code and data improvements - Preparation patches for the IOMMU runtime PM conversion - Preparation patches for OMAP4 full-chip retention support Based on a merge of v3.6-rc6, the omap-cleanup-b-for-3.7 tag (7852ec0536ca39cefffc6301dc77f8ae55592926),the cleanup-fixes-for-v3.7 tag (de6ca33a96a6bf61fcb91d3d399703e19ead9d1e), and the omap-devel-am33xx-for-v3.7 tag (11964f53eb4d9ce59a058be9999d9cfcb1ced878), due to dependencies. These patches have been tested for meaningful warnings from checkpatch, sparse, smatch, and cppcheck. Basic build, boot[1], and PM test logs are available here: http://www.pwsan.com/omap/testlogs/hwmod_prcm_clock_a_3.7/20120923173830/ ... 1. Note that the N800 boot fails due to a known issue present in the base commit: http://www.spinics.net/lists/arm-kernel/msg196034.html
