    clk: imx: clk-gate2: allow custom gate configuration · 45682922
    Stefan Agner authored
    The 2-bit gates found i.MX and Vybrid SoC support different clock
    configuration:
    
    0b00: clk disabled
    0b01: clk enabled in RUN mode but disabled in WAIT and STOP mode
    0b10: clk enabled in RUN, WAIT and STOP mode (only Vybrid)
    0b11: clk enabled in RUN and WAIT mode
    
    For some clocks, we might want to configure different behaviour,
    e.g. a memory clock should be on even in STOP mode. Add a new
    function imx_clk_gate2_cgr which allow to configure specific
    gate values through the cgr_val parameter.
