With legacy clock support gone, this is no longer needed under platform,
so move it under the clock driver itself. Make some exports be driver
internal definitions at the same time.

Clean all #ifdef's added to OMAP3 clock code to make it COMMON clk
ready, not that CONFIG_COMMON_CLK is enabled.

Convert all OMAP3 specific platform files to use COMMON clk
and keep all the changes under the CONFIG_COMMON_CLK macro check
so it does not break any existing code. At a later point switch
to COMMON clk and get rid of all old/legacy code.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/cleanup-prcm
The first set of OMAP PRM/CM-related cleanup patches for 3.8.
Prepares for the future move of the PRM/CM code to drivers/. Also
includes some prcm.[ch] cleanup patches from the WDTIMER cleanup
series that don't need external acks.
Basic test logs for this branch on top of v3.7-rc2 are here:
http://www.pwsan.com/omap/testlogs/prcm_cleanup_a_3.8/20121021123719/
But due to the number of unrelated regressions present in v3.7-rc[12],
it's not particularly usable as a testing base. With reverts, fixes,
and workarounds applied as documented in:
http://www.pwsan.com/omap/testlogs/test_v3.7-rc2/20121020134755/README.txt
the following test logs were obtained:
http://www.pwsan.com/omap/testlogs/prcm_cleanup_a_3.8/20121020231757/
which indicate that the series tests cleanly.

Move OMAP3xxx-specific CM functions & macros into cm3xxx.[ch] and
OMAP2xxx-specific macros into cm2xxx.[ch]. Move basic CM register
access functions into static inline functions in cm2xxx_3xxx.h,
leaving only OMAP2/3 hardreset functions in cm2xxx_3xxx.c.
As part of this, split the CM and hwmod code that waits for devices to
become ready into SoC-specific functions.
This is in preparation for the upcoming move of this code to drivers/.

Remove arch/arm/plat-omap/include/plat/clock.h by merging it into
arch/arm/mach-omap1/clock.h and arch/arm/mach-omap2/clock.h.
The goal here is to facilitate ARM single image kernels by removing
includes via the "plat/" symlink.

Mark each interface clock with a corresponding CM_AUTOIDLE bit with
a clkops that has the allow_idle/deny_idle function pointers populated.
This allows the OMAP clock framework to enable and disable autoidle for
these clocks.

In preparation for adding OMAP4-specific PRCM accessor/mutator
functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific
files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been
moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was
OMAP2xxx/3xxx-specific.
This process also requires the #includes in each of these files to be
changed to reference the new file name. As part of doing so, add some
comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use
"sideways includes", to indicate that these users of the PRM/CM includes
should not be doing so.
Thanks to Felipe Contreras <felipe.contreras@gmail.com> for comments on this
patch.

clock34xx_data.c now contains data for the OMAP34xx family, the
OMAP36xx family, and the OMAP3517 family, so rename it to
clock3xxx_data.c. Rename clock34xx.c to clock3xxx.c, and move the
chip family-specific clock functions to clock34xx.c, clock36xx.c, or
clock3517.c, as appropriate. So now "clock3xxx.*" refers to the OMAP3
superset.
The main goal here is to prepare to compile chip family-specific clock
functions only for kernel builds that target that chip family. To get to
that point, we also need to add CONFIG_SOC_* options for those other
chip families; that will be done in future patches, planned for 2.6.35.
OMAP4 is also affected by this. It duplicated the OMAP3 non-CORE DPLL
clkops structure. The OMAP4 variant of this clkops structure has been
removed, and since there was nothing else currently in clock44xx.c, it
too has been removed -- it can always be added back later when there
is some content for it. (The OMAP4 clock autogeneration scripts have been
updated accordingly.)
