-* 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>;
