The iwg21d comes with a 7" capacitive touch screen, therefore
add support for it.

I can't review most of this properly as I don't have access to the
schematics. Is there a way to get it ?

Is this required, won't requesting the interrupt be enough to configure
the pin properly ?

I'll check with Chris, how we could get the schematics for you.

It's actually a power supply, not an enable GPIO, but it doesn't matter
much, I don't think there's a need to declare a regulator just for the
sake of it.

This should be handled as a shared power supply, as it's also needed for
the touch screen. Biju has sent patches for the iwg20d that fixes a
probe issue due to that problem, I think you can just copy the fix.

Should the reset GPIO also be wired ? It seems to be shared with the
audio codec though, which is annoying.

Is this needed, or does requesting the interrupt in the touch screen
driver configured the GPIO to an input automatically ?
