From 9c2cc7171e08eef52110d272fdf2225d6dcd81b6 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 17 Oct 2022 22:41:06 -0700 Subject: gpiolib: of: add a quirk for reset line for Marvell NFC controller The controller is using non-standard "reset-n-io" name for its reset gpio property, whereas gpiod API expects "-gpios". Add a quirk so that gpiod API will still work on unmodified DTSes.
