Merge tag 'omap-for-v3.8/clock-signed' of git://git.kernel.org/pub/sc…

…m/linux/kernel/git/tmlind/linux-omap into next/clk

From Tony Lindgren <tony@atomide.com>:

Common clock framework for omap2+ via Paul Walmsley <paul@pwsan.com>:

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 c9d501e are here:

http://www.pwsan.com/omap/testlogs/common_clk_devel_3.8_rebase/20121112192516/

However, cleanup-prcm at c9d501e 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.

Conflicts:
	arch/arm/mach-omap2/clock33xx_data.c
	arch/arm/mach-omap2/clock3xxx_data.c
	arch/arm/mach-omap2/clock44xx_data.c

Note that this is based on a merge of the omap-for-v3.8/cleanup-prcm
and omap-for-v3.8/pm as otherwise merged in with the pm changes it
would automatically resolve into a non-booting merge for omap3 as
the smartreflex clock names were changed in the pm branch.
