Should this be "Mac mini J474"? The board file is t6020-j474s.dts and 
the root node identifies this machine as the M2 Pro Mac mini / J474s.

The fallback compatible to apple,j473-macaudio looks fine, but the sound
card model string should probably describe the actual machine rather 
than the fallback model.
