Hi,
This second version of this series improves the patch changelogs
and adds some code comments.
This patch series splits clock2xxx.c and clock34xx.c by
clock "type", e.g., DPLLs, APLLs, clksel clocks, etc. The point
is to make the code easier to read and easier to debug (by
restricting the scope of DEBUG defines). This also lays the
groundwork for further generalization of the clock code and prepares
for a multi-OMAP2/3/4 kernel.
The series also cleans up a few other minor aspects of the clock
code: the various struct omap2_clk_functions are combined; a
warning identified by sparse is resolved; unnecessary includes
have been trimmed; and some formerly-common code is now only
compiled for the chips that need it.
There are a few minor functional changes, documented in some of
the patch descriptions, but nothing significant.
Compile-tested with n8x0_defconfig, omap_2430sdp_defconfig, and
omap3_beagle_defconfig. Boot-tested on Beagle and N800.
Applies on the "for_2.6.34" branch of git://git.pwsan.com/linux-2.6
Thanks to Alexander Shishkin <virtuoso@xxxxxxxxx> for his comments.
