Subject: [PATCH V2 4/4] arm64: dts: imx8mq-evk: add wake-gpios property for pci bus
Date: Wed, 13 Dec 2023 17:28:50 +0800	[thread overview]
Message-ID: <20231213092850.1706042-5-sherry.sun@nxp.com> (raw)
In-Reply-To: <20231213092850.1706042-1-sherry.sun@nxp.com>

The host wake pin is a standard feature in the PCIe bus specification,
so we add this property under PCI dts node to enable the host wake
function.
