-* 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 {
