Merge tag 'omap-devel-late-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into late/soc

These changes take us a step closer to merging the common clock
framework for omap but unfortunately these patches were not
ready for merging earlier. See also the notes below on the
dependencies these patches have, they are based on a merge
of sereral branches already merged.

From Paul Walmsley <paul@pwsan.com>:

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.
