RK3588(s) uses a several SPDIF transmitters which are software
compatible with those found in RK3568. This series adds the required
device tree nodes in SoC .dtsi and enables the dedicated optical
SPDIF output on the H96 Max V58.
Note that only SPDIF 0/1 are meant as externally connected outputs,
while SPDIF 2/3/4/5 are internally routed to the various display
encoders inside the SoC. Thus, using SPDIF 0/1 only requires their
device tree nodes to be enabled (provided that the signal is routed
somewhere usable on the board itself), while the rest rely on driver
support on the display connector side and are therefore not touched
here.
