Subject: [PATCH 2/3] ARM: dts: imx6: rdu2: Disable WP for USDHC2 and USDHC3
Date: Wed, 22 May 2019 00:12:26 -0700	[thread overview]
Message-ID: <20190522071227.31488-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190522071227.31488-1-andrew.smirnov@gmail.com>

RDU2 production units come with resistor connecting WP pin to
correpsonding GPIO DNPed for both SD card slots. Drop any WP related
configuration and mark both slots with "disable-wp".
