The g12a audio subsystem, which is a derivative of the axg subsystem, provides a dedicated reset line for each of the audio components. The axg did not provide that and it is unclear if/when these reset are required. The reset already helped solve a channel mapping issue on the tdm formatter devices. Let's add the reset binding for the other components, so we can describe this in DT. We'll use it later on in the driver when/if needed.

* 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>;
|

sound-dai = <&tdmif_c>;
|

dai-format = "i2s";
