Subject: [PATCH v5 1/3] dt-bindings: exynos-dw-mshc-common: add exynos7885 variants
Date: Sun, 12 Mar 2023 20:58:50 +0300	[thread overview]
Message-ID: <640e143e.050a0220.73b97.1b14@mx.google.com> (raw)

Some Samsung Exynos boards using the arm64 architecture have DW MMC
controllers configured for a 32-bit data bus but a 64-bit FIFO. On these
systems the 64-bit FIFO registers must be accessed in two 32-bit halves.

Add two new compatible strings, "samsung,exynos7885-dw-mshc" and
"samsung,exynos7885-dw-mshc-smu" respectively, to denote exynos7885
boards that need this quirk. But it's very possible that all
"samsung,exynos7-dw-mshc" boards are actually affected.
