fsl,mqs audio CODEC

Required properties:

  - compatible : Must contain one of "fsl,imx6sx-mqs", "fsl,codec-mqs"

		"fsl,imx8qm-mqs", "fsl,imx8qxp-mqs", "fsl,imx93-mqs".

  - clocks : A list of phandles + clock-specifiers, one for each entry in

	     clock-names

  - clock-names : "mclk" - must required.

		  "core" - required if compatible is "fsl,imx8qm-mqs", it

		           is for register access.

  - gpr : A phandle of General Purpose Registers in IOMUX Controller.

	  Required if compatible is "fsl,imx6sx-mqs".

Required if compatible is "fsl,imx8qm-mqs":

  - power-domains: A phandle of PM domain provider node.

  - reg: Offset and length of the register set for the device.

Example:

mqs: mqs {

	compatible = "fsl,imx6sx-mqs";

	gpr = <&gpr>;

	clocks = <&clks IMX6SX_CLK_SAI1>;

	clock-names = "mclk";

	status = "disabled";

};

mqs: mqs@59850000 {

	compatible = "fsl,imx8qm-mqs";

	reg = <0x59850000 0x10000>;

	clocks = <&clk IMX8QM_AUD_MQS_IPG>,

		 <&clk IMX8QM_AUD_MQS_HMCLK>;

	clock-names = "core", "mclk";

	power-domains = <&pd_mqs0>;

	status = "disabled";

  Medium quality sound (MQS) is used to generate medium quality audio

  via a standard GPIO in the pinmux, allowing the user to connect

  stereo speakers or headphones to a power amplifier without an

  additional DAC chip.
