On these systems the 64-bit FIFO registers must be accessed in two 32-bit halves. Add two new compatible strings, "samsung,exynos78xx-dw-mshc" and "samsung,exynos78xx-dw-mshc-smu" respectively, to denote exynos78xx boards that need this quirk. But it's very possible that all "samsung,exynos7-dw-mshc" boards are actually affected. --- .../devicetree/bindings/mmc/samsung,exynos-dw-mshc.yaml | 2 ++ 1 file changed, 2 insertions(+) diff --git a/Documentation/devicetree/bindings/mmc/samsung,exynos-dw-mshc.yaml b/Documentation/devicetree/bindings/mmc/samsung,exynos-dw-mshc.yaml index fdaa18481..a72a67792 100644 --- a/Documentation/devicetree/bindings/mmc/samsung,exynos-dw-mshc.yaml +++ b/Documentation/devicetree/bindings/mmc/samsung,exynos-dw-mshc.yaml @@ -22,6 +22,8 @@ properties: - samsung,exynos5420-dw-mshc-smu - samsung,exynos7-dw-mshc - samsung,exynos7-dw-mshc-smu + - samsung,exynos78xx-dw-mshc + - samsung,exynos78xx-dw-mshc-smu - axis,artpec8-dw-mshc reg:
