Agreed. With only 8 pins, listing the channels explicitly in the DT
costs little, and it keeps the door open for the GPIO support.

Maxime, if you drop the fallback, I think the commit message of patch
1/2 should lose its last sentence too ("If no ADC chan description is
represented, all channels will be exposed as analog inputs."), since
it would no longer describe what the driver does.

Thanks,

Rodolfo
