Subject: [PATCH] ARM: dts: am33xx: add aliases for mmc interfaces
Date: Thu, 28 Jan 2021 15:56:44 +0000 [thread overview]
Message-ID: <20210128155644.6553-1-mans@mansr.com> (raw)
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.
