I was confused by the vendor dts. I found them enabled rk809 audio
codec [1],but also disabled
the I2S1 TDM audio controller. I'm not sure what they want to do.
But from my side I agree this should not be added. And the i2s1_8ch
node in current dts
should be removed as well.
Thanks,
Tianling.

Yeah, I did miss some properties here. There are some minor differences between
vendor bindings and upstream ones.
