Subject: [PATCH 3/4] arm64: dts: qcom: msm8998: Add SDC2 control pins
Date:   Thu, 15 Nov 2018 10:18:10 -0700
Message-Id: <1542302291-6864-4-git-send-email-jhugo@codeaurora.org>
In-Reply-To: <1542302291-6864-1-git-send-email-jhugo@codeaurora.org>
References: <1542302291-6864-1-git-send-email-jhugo@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The SDC2 control pins are typically used to manage sleep.
