[PATCH 08/36] gpio: aspeed: use new pinctrl GPIO helpers

From: Bartosz Golaszewski <hidden>
Date: 2023-10-03 14:51:55

From: Bartosz Golaszewski <redacted>

Replace the pinctrl helpers taking the global GPIO number as argument
with the improved variants that instead take a pointer to the GPIO chip
and the controller-relative offset.

Ah, this looks like it removes a bug too. Nice.

I sent a separate patch that fixes this issue for backporting, once
the other one is in next, we can update this series.
