Hi Mark & Russell:

thanks for your replay, what your say is right, those dt is merely=20
describing the Linux kernel internals.
Instead of transmit cpu-of-node & codec-name & codec-dai-name through=20
dt, i can give those an const
name to rockchip-hdmi-audio.c .

In that way, dt will only need compatible for creating sound device. is=
=20
it ok  ?
sound {
     compatible =3D "rockchip,rk3288-hdmi-audio";
     status =3D "okay";
}
could you give me some advises.


Best Regards.
