2016-03-27clk: rockchip: Add support for multiple clock providersXing Zheng8-118/+229
There are need to support Multi-CRUs probability in future, but it is not supported on the current Rockchip Clock Framework. Therefore, this patch add support a provider as the parameter handler when we call the clock register functions for per CRU.

2016-03-27clk: rockchip: allow varying mux parameters for cpuclk pll-sourcesXing Zheng7-11/+45
Thers are only two parent PLLs that APLL and GPLL for core on the previous SoCs (RK3066/RK3188/RK3288/RK3368). Hence, we set fixed GPLL as alternate parent when core is switching freq. Since RK3399 big.LITTLE architecture, we need to select and adapt more PLLs (ALPLL/ABPLL/DPLL/GPLL) sources.

2016-03-17clk: bcm2835: correctly enable fractional clock supportMartin Sperl1-6/+39
The current driver calculates the clock divider with fractional support enabled. But it does not enable fractional support in the control register itself resulting in an integer only divider, but in clk_set_rate responds back the fractionally divided clock frequency. This patch enables fractional support in the control register whenever there is a fractional bit set in the requested clock divider. Mash clock limits are are also handled for the PWM clock applying the correct divider limits (2 and max_int) applicable to basic fractional divider support (mash order of 1). It also adds locking to protect the read/modify/write cycle of the register modification.
