-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.

-
-mqs: mqs {
- compatible = "fsl,imx6sx-mqs";
- gpr = <&gpr>;
- clocks = <&clks IMX6SX_CLK_SAI1>;

+ 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.
