Subject: [PATCH 3/7] gpiolib: of: add quirk for locating reset lines with legacy bindings
Date: Tue, 11 Oct 2022 15:19:31 -0700 [thread overview]
Message-ID: <20221011-gpiolib-quirks-v1-3-e01d9d3e7b29@gmail.com> (raw)
In-Reply-To: <20221011-gpiolib-quirks-v1-0-e01d9d3e7b29@gmail.com>
Some legacy mappings used "gpio[s]-reset" instead of "reset-gpios",
add a quirk so that gpiod API will still work on unmodified DTSes.
