    clk: add CLK_SET_RATE_NO_REPARENT flag · 819c1de3
    James Hogan authored
    Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes
    being reparented during clk_set_rate.
    
    To avoid breaking existing platforms, all callers of clk_register_mux()
    are adjusted to pass the new flag. Platform maintainers are encouraged
    to remove the flag if they wish to allow mux reparenting on set_rate.
