* rk_cru is a cru driver that needs to be subclassed by the real CRU driver * rk_clk_pll handle the pll type clock on RockChip SoC, it's only read only for now. * rk_clk_composite handle the different composite clock types (with gate, with mux etc ...) * rk_clk_gate handle the RockChip gates * rk_clk_mux handle the RockChip muxes (unused for now) * Only clocks for supported devices are supported for now, the rest will be added when driver support comes * The assigned-clock* property are not handled for now so we rely a lot on the bootloader to setup some initial values for some clocks.
