    ARM: imx: add common clock support for fixup mux · a49e6c4b
    Liu Ying authored
    One register may have several fields to control some clocks. It
    is possible that the read/write values of some fields may map to
    different real functional values, so writing to the other fields
    in the same register may break a working clock tree. A real case
    is the aclk_podf field in the register 'CCM Serial Clock Multiplexer
    Register 1' of i.MX6Q/SDL SoC. This patch introduces a fixup hook
    for multiplexer clock which is called before writing a value to
    clock registers to support this kind of multiplexer clocks.
