Subject: [PATCH] ARM: dts: am33xx: add aliases for mmc interfaces
Date:   Thu, 28 Jan 2021 15:56:44 +0000

Without DT aliases, the numbering of mmc interfaces is unpredictable.
Adding them makes it possible to refer to devices consistently.  The
popular suggestion to use UUIDs obviously doesn't work with a blank
device fresh from the factory.

See fa2d0aa96941 "mmc: core: Allow setting slot index via device tree
alias" for more discussion.
