MSM based Soundwire audio codec



Required properties:

 - compatible = "qcom,msm-sdw-codec";

 - reg: Specifies the soundwire codec base address for MSM digital

	soundwire core registers.

 - interrupts: Specifies the soundwire master interrupt number to Apps processor.

 - interrupt-names: Specify the interrupt name from soundwire master.

 - swr_master: This node is added as a child of MSM soundwire codec

	       and uses already existing driver soundwire master.

	       And there is/are subchild node(s) under soundwire master

	       which is also existing driver WSA881x that represents

	       soundwire slave devices.



Example:



msm_sdw_codec: qcom,msm-sdw-codec@152c1000 {

	compatible = "qcom,msm-sdw-codec";

	reg = <0x152c1000 0x0>;

	interrupts = <0 161 0>;

	interrupt-names = "swr_master_irq";



	swr_master {

		compatible = "qcom,swr-wcd";

		#address-cells = <2>;

		#size-cells = <0>;



		wsa881x_1: wsa881x@20170212 {

			compatible = "qcom,wsa881x";

			reg = <0x00 0x20170212>;

			qcom,spkr-sd-n-gpio = <&tlmm 80 0>;

		};

	};

};
