Thanks! I don't claim this is the correct way to fix this, just that it  
works.

Specifically, the two things I found that got gpio-hog working were

   (a) adding an explicit probe instead of DM_FLAG_PROBE_AFTER_BIND in gpio_post_bind(), or

   (b) adding a .bind function in U_BOOT_DRIVER(mt7981_pinctrl) like

     static int mtk_pinctrl_mt7981_bind(struct udevice *dev)
     {
     	dev_or_flags(dev, DM_FLAG_PROBE_AFTER_BIND);
     	return 0;
     }

However, presumably (b) isn't right as it would (presumably) need  
repeating in lots of other pinctrl drivers?

Best wishes,

Chris.
