Subject: [PATCH 3/3] arm64: dts: rockchip: rock-3a: add io domain properties
Date:   Mon,  4 Sep 2023 13:58:16 +0200
Message-Id: <20230904115816.1237684-4-s.hauer@pengutronix.de>
In-Reply-To: <20230904115816.1237684-1-s.hauer@pengutronix.de>

Tell the pinctrl driver that it shall wait for the io domain driver
before configuring pins. Also add exceptions for the pins needed to
access the PMIC.
