Subject: [PATCHv3 5/7] ARM: dts: exynos5422: use wp-gpio method to detect sd-card
Date: Thu, 20 Sep 2018 17:58:24 +0000 [thread overview]
Message-ID: <20180920175826.1284-6-linux.amoon@gmail.com> (raw)
In-Reply-To: <20180920175826.1284-1-linux.amoon@gmail.com>
add the Write Protect GPIO property for sdcard, to fix
the warning message during boot time.
