Subject: [PATCH v3 04/10] gpiolib: of: add quirk for locating reset lines with legacy bindings
Date: Mon, 17 Oct 2022 22:41:05 -0700	[thread overview]
Message-ID: <20221011-gpiolib-quirks-v3-4-eae9cc2ed0a1@gmail.com> (raw)
In-Reply-To: <20221011-gpiolib-quirks-v3-0-eae9cc2ed0a1@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.
