[PATCH 23/23] MIPS: mobileye: eyeq5: map GPIOs to pins using gpio-ranges

From: Théo Lebrun
Date: Wed Feb 14 2024 - 11:29:55 EST


Create a mapping between the GPIO controllers and the pin controllers.
GPIO is handled in a one-instance-per-bank manner while pinctrl is done
with a single instance for both pin banks.

See gpio-ranges documentation:
Documentation/devicetree/bindings/gpio/gpio.txt
