To recap, the pxa3xx driver uses the pinctrl-single driver since a while

I guess we need to discuss with Tony and Haojian if pinctrl-single should
ever implement that or if it is thought as having GPIO and pin
control orthogonally.
Sure why not as long as pinctrl-single can decipher the gpio
number and then call the GPIO framework.
Hmm, but the call is coming from the GPIO framework already. I'm not
quite following.
Anyway. it seems that teaching the pinctrl-single driver needs to learn
setting directions at all, so for now, I'd like to get the patch that
works around that merged for 4.19. I'll reword the commit log a bit and
resend.
Thanks,
Daniel
