OMAP2+ clock: revise omap2_clk_{disable,enable}()
OMAP2/3 clock: combine OMAP2 & 3 boot-time MPU rate change code
OMAP clockdomain: if no autodeps exist, don't try to add or remove them
OMAP hwmod: add hwmod class support
OMAP hwmod: convert header files with static allocations into C files
OMAP hwmod: convert hwmod to use hardware clock names rather than clkdev dev+con
OMAP clock: add omap_clk_get_by_name() for use by OMAP hwmod core code
OMAP3: clock: add capability to change rate of dpll4_m5_ck_3630
OMAP4 clock: drop the ALWAYS_ENABLED clock flag
OMAP clock: drop RATE_FIXED clock flag
