Subject: [PATCH] arm64: dts: imx8mm: Enable SNVS power key according to board design
Date:   Thu, 13 Jun 2019 10:01:04 +0800
Message-Id: <20190613020104.24612-1-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Anson Huang <Anson.Huang@nxp.com>

The SNVS power key depends on board design, by default it should
be disabled in SoC DT and ONLY be enabled on board DT if it is
wired up.
