Subject: [PATCH v2 6/9] gpiolib: of: add a quirk for reset line for Cirrus CS42L56 codec
Date:   Fri, 14 Oct 2022 10:54:30 -0700

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.
