[PATCH v1 5/6] ARM: boards: protonic-imx6: Add emmc_usdhc machine data variable
Oleksij Rempel

Wed Aug 18 05:19:44 PDT 2021
From: Robin van der Gracht <robin at 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'.
