Hi Mark & Russell:
thanks for your replay, what your say is right, those dt is merely describing the Linux kernel internals. Instead of transmit cpu-of-node & codec-name & codec-dai-name through 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 it ok ? sound { compatible = "rockchip,rk3288-hdmi-audio"; status = "okay"; } could you give me some advises.
Best Regards.

Including details like this (because ASoC needs a separate DT node) is the wrong approach.
And indeed there should be no Linux-internal reason for that - we should be able to use whatever DT node makes sense, if there's some reason that's not possible we should fix that (we do have several drivers doing this sort of thing already though).
