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>;
+ };
+ };
