Subject: [PATCH] ARM: dts: imx6dl-yapp4: Use aliases to set custom MMC device indexes
Date: Fri, 30 Apr 2021 15:53:15 +0200 [thread overview]
Message-ID: <1619790795-8375-1-git-send-email-michal.vokac@ysoft.com> (raw)
Until commit fa2d0aa96941 ("mmc: core: Allow setting slot index via
device tree alias") was introduced, our usdhc3 and usdhc4 devices
were enumerated as mmc0 and mmc1. The mmc1 device is used to boot/update
the board and its name must be fixed.
With the referenced commit, aliases from imx6qdl.dtsi took effect.
Override the aliases to get back the original device indexes.
