Subject: [PATCH v1 5/6] ARM: boards: protonic-imx6: Add emmc_usdhc machine data variable
Date: Wed, 18 Aug 2021 14:19:44 +0200
Message-ID: <20210818121945.26089-6-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210818121945.26089-1-o.rempel@pengutronix.de>

From: Robin van der Gracht <robin@protonic.nl>

The i.MX6 ultralite only has 2 usdhc ports which will be indexed as '0'
and '1'. The bbu setup code assumes it is attached as '/dev/mmc2'.
