+fsl,aud2htx The AUD2HTX is a digital module that provides a bridge between
+the Audio Subsystem and the HDMI RTX Subsystem.
+
+Required properties:
+
+- compatible: Must contain one of "fsl,imx8mp-aud2htx".
+- reg: Offset and length of the register set for the device.
+- interrupts: <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and
+ level information for the interrupt. This should be
+ encoded based on the information in section 2)
+ depending on the type of interrupt controller you
+ have.
+- clocks: A list of phandles + clock-specifiers, one for each
+ entry in clock-names
+- clock-names: Must contain "bus"
+
+Optional properties:
+- dmas: Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names: One dmas have to be defined, "tx".
+
+Example:
+
+aud2htx: aud2htx@30cb0000 {
+ compatible = "fsl,imx8mp-aud2htx";
+ reg = <0x30cb0000 0x10000>;
+ interrupts = <GIC_SPI 130 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&audiomix_clk IMX8MP_CLK_AUDIOMIX_AUD2HTX_IPG>;
+ clock-names = "bus";
+ dmas = <&sdma2 26 2 0>;
+ dma-names = "tx";
+ power-domains = <&audiomix_pd>;
+ status = "disabled";
+};
