Hi Tony
The following changes since commit c9d501e5cb0238910337213e12a09127221c35d8:
Merge tag 'omap-cleanup-b2-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/cleanup-prcm (2012-11-09 14:13:43 -0800)

ARM: OMAP2+: clock: Cleanup !CONFIG_COMMON_CLK parts (2012-11-12 19:18:51 -0700)
- ----------------------------------------------------------------
Convert the OMAP2+ clock code and data to rely on the common
clock framework for internal bookkeeping and the driver API.
Basic test logs for this branch on top of Tony's cleanup-prcm branch
at commit c9d501e5cb0238910337213e12a09127221c35d8 are here:
http://www.pwsan.com/omap/testlogs/common_clk_devel_3.8_rebase/20121112192516/
However, cleanup-prcm at c9d501e5 does not include some fixes
that are needed for a successful test. With several reverts,
fixes, and workarounds applied, the following test logs were
obtained:
http://www.pwsan.com/omap/testlogs/TEST_common_clk_devel_3.8_rebase/20121112192300/
which indicate that the series tests cleanly.
N.B. The common clock data addition patches result in many
checkpatch warnings of the form "WARNING: static const char *
array should probably be static const char * const". However, it
appears that resolving these would require changes to the CCF
itself. So the resolution of these warnings is being postponed
until that can be coordinated.
These patches result in a ~55KiB increase in runtime kernel memory
usage when booting omap2plus_defconfig kernels.
