Subject: [PATCH] ARM: dts: da850-evm: add WP and CD to MMC
Date: Fri, 30 Mar 2018 11:52:34 -0500 [thread overview]
Message-ID: <1522428754-28337-1-git-send-email-aford173@gmail.com> (raw)
The legacy mode uses the write protect and card detect but DT
has not. This patch enables the pinmuxing and detection for
WP and CD.
