About "type" property on OF graph DT, your opinion was that
it is not needed, and HDMI driver can handle it.
But I noticed that it doesn't work for HDMI sound side.
Below case, port 0 to 3 is for HDMI video out, and port 4 - 5 are for
HDMI sound.
This is located in HDMI video out DT, so, port 0 - 3 can be handled by
HDMI video driver. but port 4 - 5 will be handled by HDMI sound driver
which is very generic driver, and it references this port.
In ALSA side, in this case HDMI sound is handled as 1st and 2nd DAI.
This means, port4 should 1st, port5 should be 2nd in ALSA.
it is impossible to handle it without "type" property.
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
du_out_rgb: endpoint {
};
};
port@1 {
reg = <1>;
du_out_hdmi0: endpoint {
};
};
port@2 {
reg = <2>;
du_out_hdmi1: endpoint {
};
};
port@3 {
reg = <3>;
du_out_lvds0: endpoint {
};
};
port@4 {
type = "sound";
du_out_hdmi_snd0: endpoint {
};
};
port@5 {
type = "sound";
du_out_hdmi_snd1: endpoint {
};
};
};
