Subject: [PATCH AUTOSEL 5.4 01/19] ARM: dts: am33xx: add aliases for mmc interfaces
Date: Mon, 29 Mar 2021 18:22:44 -0400
Message-ID: <20210329222303.2383319-1-sashal@kernel.org> (raw)

From: Mans Rullgard <mans@mansr.com>

[ 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.
