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:

...

1. Note that the N800 boot fails due to a known issue present in the
   base commit:
