This is not actually a separate physical device from the main dw-hdmi
device.  What you are doing is merely describing the Linux kernel
internals in DT, which is not what DT is supposed to be about.  DT is
supposed to describe the hardware in an operating system independent
manner.

Including details like this (because ASoC needs a separate DT node) is
the wrong approach.
