Subject: [PATCH 4/7] gpiolib: of: add a quirk for reset line for Marvell NFC controller
Date: Tue, 11 Oct 2022 15:19:32 -0700	[thread overview]
Message-ID: <20221011-gpiolib-quirks-v1-4-e01d9d3e7b29@gmail.com> (raw)
In-Reply-To: <20221011-gpiolib-quirks-v1-0-e01d9d3e7b29@gmail.com>

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.
