Subject: [PATCH 02/24] pinctrl: stm32: use gpio-ranges instead of alias
Date: Sun, 20 Feb 2022 13:47:14 +0100 [thread overview]
Message-ID: <20220220124736.3052502-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20220220124736.3052502-1-a.fatoum@pengutronix.de>
Upstream device tree doesn't feature aliases and we don't really need
it, as the gpio-ranges property has a GPIO controller offset cell.
Use it instead.
