clk: add pxa clocks infrastructure Add a the common code used by all PXA variants. This is the first step in the transition from architecture defined clocks (in arch/arm/mach-pxa) towards clock framework. The goal is to have the same features (and not all the features) of the existing clocks, and enable the transition of PXA to device-tree. All PXA rely on a "CKEN" type clock, which : - has a gate (bit in CKEN register) - is generated from a PLL, generally divided - has an alternate low power clock Each variant will specialize the CKEN clock : - pxa25x have no low power clock - pxa27x in low power use always the 13 MHz ring oscillator - pxa3xx in low power have specific dividers for each clock The device-tree provides a list of CLK_* (ex: CLK_USB or CLK_I2C) to get a handle on the clock. While pxa-clock.h will describe all the clocks of all the variants, each variant will only use a subset of it.

clk: add pxa27x clock drivers Move pxa27x clock drivers from arch/arm/mach-pxa to driver/clk. In the move : - convert to new clock framework legacy clocks - provide clocks as before for platform data based boards - provide clocks through devicetree Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Mike Turquette <mturquette@linaro.org> 2014-07-31 04:51:02 +08:00			`obj-$(CONFIG_PXA27x) += clk-pxa27x.o`
