From 44da0a51032f3d90a441bd80c2efe68532104980 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 26 Jan 2010 20:13:08 -0700 Subject: OMAP2xxx clock: move sys_clk code into mach-omap2/clkt2xxx_sys.c Move the sys_clk clock functions from clock2xxx.c to mach-omap2/clkt2xxx_sys.c. This is intended to make the clock code easier to understand, since all of the functions needed to manage the sys_clk 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 sys_clk clock alone. This should reduce unnecessary console noise when debugging. 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-omap2xxx/ directory, rather than shared with other chip types that don't use this clock type. Thanks to Alexander Shishkin for his comments to improve the patch description.
