All other Rockchip decoder/encoder nodes use the video-codec nodename,
e.g. see the av1d related node below. Is there any special reason why
this cannot follow that pattern for nodename consistency?
This was something I tried to bring up in v3 [1], however only the reg
range part was addressed in v4.
My main concern is that I want to send an updated U-Boot RK3582 support
series [2][3] that will need to mark one or both of the two rkvdec cores
as status=fail depending on a value in OTP. This is done in a DT fixup
and uses the nodename for simplicity.
