Subject: [PATCH 3/4] arm64: dts: imx8mp-evk: add host-wake-gpio property for pci bus
Date: Fri,  8 Dec 2023 17:13:54 +0800	[thread overview]
Message-ID: <20231208091355.1417292-4-sherry.sun@nxp.com> (raw)
In-Reply-To: <20231208091355.1417292-1-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.
