    Subject[PATCH v2 02/13] Documentation: mfd: Add DT bindings for i.MX Audiomix
    Date
    The i.MX Audiomix is a mix of clock gates, reset bits
    and some other i.MX audio specific functionalities.
    Add information for the MFD, its clock and reset controllers.

    +Freescale i.MX Audiomix
    +======================================
    +
    +Audiomix is a conglomerate of different functionalities.
    +
    +Required properties:
    +- compatible: Should be "fsl,<chip>-mix" for the MFD device
    + Should be"fsl,<chip>-audiomix-clk" for the clock controller
    + Should be"fsl,<chip>-audiomix-reset" for the reset controller
    + Some functionalities of the audiomix will be registered as syscon.
    +- reg: should be register base and length as documented in the
    + datasheet
    +
    +example:
    + audiomix: audiomix@30e20000 {
    + compatible = "fsl,imx8mp-mix";
    + reg = <0x30e20000 0x10000>;
    +
    + audiomix_clk: clock-controller {
    + compatible = "fsl,imx8mp-audiomix-clk";
    + #clock-cells = <1>;
    + clocks = <&clk IMX8MP_CLK_AUDIO_ROOT>,
    + <&clk IMX8MP_CLK_AUDIO_AHB>,
    + <&clk IMX8MP_CLK_AUDIO_AXI_DIV>;
    + clock-names = "audio_root",
    + "audio_ahb",
    + "audio_axi_div";
    + };
    +
    + audiomix_reset: reset-controller {
    + compatible = "fsl,imx8mp-audiomix-reset";
    + #reset-cells = <1>;
    + };
    + };
