[PATCH v3 06/10] gpiolib: of: add a quirk for reset line for Cirrus CS42L56 codec

From: Dmitry Torokhov
Date: Tue Oct 18 2022 - 01:42:10 EST


The controller is using non-standard "cirrus,gpio-nreset" 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.
