* Amlogic HDMI Tx control glue



Required properties:

- compatible: "amlogic,g12a-tohdmitx" or

	      "amlogic,sm1-tohdmitx"

- reg: physical base address of the controller and length of memory

       mapped region.

- #sound-dai-cells: should be 1.

- resets: phandle to the dedicated reset line of the hdmitx glue.



Example on the S905X2 SoC:



tohdmitx: audio-controller@744 {

	compatible = "amlogic,g12a-tohdmitx";

	reg = <0x0 0x744 0x0 0x4>;

	#sound-dai-cells = <1>;

	resets = <&clkc_audio AUD_RESET_TOHDMITX>;

};



Example of an 'amlogic,axg-sound-card':



sound {

	compatible = "amlogic,axg-sound-card";



[...]



	dai-link-x {

		sound-dai = <&tdmif_a>;

		dai-format = "i2s";

		dai-tdm-slot-tx-mask-0 = <1 1>;



		codec-0 {

			sound-dai = <&tohdmitx TOHDMITX_I2S_IN_A>;

		};



		codec-1 {

			sound-dai = <&external_dac>;

		};

	};



	dai-link-y {

		sound-dai = <&tdmif_c>;

		dai-format = "i2s";

		dai-tdm-slot-tx-mask-0 = <1 1>;



		codec {

			sound-dai = <&tohdmitx TOHDMITX_I2S_IN_C>;

		};

	};



	dai-link-z {

		sound-dai = <&tohdmitx TOHDMITX_I2S_OUT>;



		codec {

			sound-dai = <&hdmi_tx>;

		};

	};

};
