* Amlogic HDMI Tx control glue
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: "amlogic,g12a-tohdmitx"
|
||||||
|
- reg: physical base address of the controller and length of memory
|
||||||
|
mapped region.
|
||||||
|
- #sound-dai-cells: should be 1.
|
||||||
|
|
||||||
|
Example on the S905X2 SoC:
|
||||||
|
|
||||||
|
tohdmitx: audio-controller@744 {
|
||||||
|
compatible = "amlogic,g12a-tohdmitx";
|
||||||
|
reg = <0x0 0x744 0x0 0x4>;
|
||||||
|
#sound-dai-cells = <1>;
|
||||||
|
};
|
||||||
|
|
||||||
|
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>;
|
||||||
|
};
|
||||||
|
};
|
||||||
|
|
||||||
|

|
||||||
|
sound-dai = <&tohdmitx TOHDMITX_I2S_OUT>;
|
||||||
|
|
||||||
|
codec {
|
||||||
|
sound-dai = <&hdmi_tx>;
|
||||||
|
};
|
||||||

};
