From: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Some devices may use both gpio0 and gpio1 to independently switch
the speaker and the headphone.

Add support for that.

This is starting to be a bit messy, the initial gpios were really 
intended for speakers and should be clearly referring to speakers now. 
the TGL quirk really means gpio1 is used instead of gpio0, and I can't 
figure out what the 'pa' prefix is needed for.

Can I suggest the attached cleanup patch be added first? That would make 
it clearer and more readable IMHO. Compile-tested only since I don't 
have hardware.

Thanks!

Makes sense. I'll place it before the first patch, rebase them,
test and re-submit.
