OMAP1 clock: convert mach-omap1/clock.h to mach-omap1/clock_data.c The OMAP1 clock code currently #includes a large .h file full of static data structures. Instead, define the data in a .c file. Russell King <linux@arm.linux.org.uk> proposed this new arrangement: http://marc.info/?l=linux-omap&m=125967425908895&w=2 This patch also deals with most of the flagrant checkpatch violations. While here, separate the mpu_rate data structures out into their own files, opp.h and opp_data.c. In the long run, these mpu_rate tables should be replaced with OPP code. Also includes a patch from Felipe Balbi <felipe.balbi@nokia.com> to mark omap1_clk_functions as __initdata to avoid a section warning: http://patchwork.kernel.org/patch/64366/ Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Felipe Balbi <felipe.balbi@nokia.com> Cc: Nishanth Menon <nm@ti.com>

ARM: OMAP1: Move dpll1 rates selection from config to runtime For still better multi-OMAP1 support, expand omap1_rate_table with flags for different SoC types and match them while selecting clock rates. The idea is stolen from current omap24xx clock rate selection algorithm. Since clkdev platform flag definitions are reused here, those had to be expanded with one extra entry for OMAP1710 subtype, as this is the only SoC for which we allow selection of the highest, 216 MHz rate. Once done, remove no longer needed clock rate configure time options. Tested on Amstrad Delta.
