Subject: [PATCH v2 2/2] gpiolib: of: add polarity quirk for Freescale PCIe controller
Date: Sat, 29 Oct 2022 21:40:47 -0700 [thread overview]
Message-ID: <20221030044047.423859-2-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20221030044047.423859-1-dmitry.torokhov@gmail.com>
Bindings for Freescale PCIe controller use a separate property called
"reset-gpio-active-high" to control polarity of its reset line, add it
to the list of quirks in gpiolib so that gpiod API can be used in the
driver.
