[PATCH v3 05/10] gpiolib: of: add a quirk for reset line for Marvell NFC controller

From: Dmitry Torokhov
Date: Tue Oct 18 2022 - 01:41:53 EST


The controller is using non-standard "reset-n-io" name for its reset
gpio property, whereas gpiod API expects "<name>-gpios". Add a quirk
so that gpiod API will still work on unmodified DTSes.
