Subject: [PATCH v2 3/3] arm64: dts: qcom: msm8998-mtp: Add external SD
Date: Thu, 15 Nov 2018 13:44:55 -0700 [thread overview]
Message-ID: <1542314695-24071-4-git-send-email-jhugo@codeaurora.org> (raw)
In-Reply-To: <1542314695-24071-1-git-send-email-jhugo@codeaurora.org>
The externally accessible SD card slot on the MTP is driven by SDCC2.
Wire it up for use.
