Subject: [PATCH v2 2/4] dt-bindings: mmc: Add support for BCM2712 SD host controller
Date: Fri, 10 May 2024 16:35:28 +0200
Message-ID: <1f0c4fa62d6849753e2138cce5498693cfc3a230.1715332922.git.andrea.porta@suse.com>

The BCM2712 has an SDHCI capable host interface similar to the one found
in other STB chipsets. Add the relevant compatible string and relative
example.
