[PATCH AUTOSEL 4.19 01/15] ARM: dts: am33xx: add aliases for mmc interfaces

[Sasha Levin]

From: Mans Rullgard <mans@xxxxxxxxx>

[ Upstream commit 9bbce32a20d6a72c767a7f85fd6127babd1410ac ]

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