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.)

mach-omap2/clkt34xx_dpll3m2.c
Split the DPLL3 M2 divider clock functions out of clock34xx.c and move
them into mach-omap2/clkt34xx_dpll3m2.c. This is intended to make the
clock code easier to understand, since all of the functions needed to
manage the OMAP3 DPLL3 M2 divider are now located in their own file,
rather than being mixed with other, unrelated functions.
Clock debugging is also now more finely-grained, since the DEBUG macro
can now be defined for the DPLL3 M2 clock alone. This should reduce
unnecessary console noise when debugging DVFS.
Also, if at some future point the mach-omap2/ directory is split
into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap34xx/
directory, rather than shared with other chip types that don't use this
clock type.
This patch also lays the groundwork to skip compilation of this
code on OMAP3 chips that don't support DVFS (e.g., AM35xx) via
the Makefile, rather than via #ifdefs.
Thanks to Alexander Shishkin <virtuoso@slind.org> for his comments to
improve the patch description.
