It was found that some firmware versions initialized the pll rates using
suboptimal parameters to achieve frequencies the actual rate table contained
better parameters for.
Therefore this series first adds the possibility to create pll-specific flags
and then adds a flag to adjust the pll rate on init to the parameters from
the rate table.
changes since v1:
- move population of pll_mux before registering the core pll clock
null pointer exception in the _set_rate callback when called from init
Heiko Stuebner (4):
clk: rockchip: add ability to specify pll-specific flags
clk: rockchip: setup pll_mux data earlier
clk: rockchip: add optional sync to pll rate parameters
clk: rockchip: add ROCKCHIP_PLL_SYNC_RATE flag to some plls
