* 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>;
};
};
};
