Subject: [PATCH 2/2] arm64: dts: imx8mn-ddr4-evk: add phy-reset-gpios for fec1
Date: Mon, 21 Oct 2019 09:21:41 +0000	[thread overview]
Message-ID: <1571649512-24041-2-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1571649512-24041-1-git-send-email-peng.fan@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

We should not rely on U-Boot to configure the phy reset.
So introduce phy-reset-gpios property to let Linux handle phy reset
itself.
