As I've told, there are only two GPIO pins, so only "0=X 1=Y", plus
ogain mixer control.

GPIO pins are bidirectional, but I have doubt that input or high
impedance ("disable") state could be used to control something. "keep"
is also useless, as by default these pins are disabled. So you have only
"set" and "clear".

Yes, that should work.

I don't think it is required.
