Add an A733-specific compatible string, with the D1 as fallback. Signed-off-by: Jerome Brunet --- Like the A523, the A733 3 first MMC controllers share the same IP block. The 4th is known to be incompatible with 3 first. Unlike the A523, the A733 4th controller is not dedicated to eMMC. This 4th controller access the memory through a different bus. This is not supported (or tested) yet. It will require a different compatible when the time comes. --- Documentation/devicetree/bindings/mmc/allwinner,sun4i-a10-mmc.yaml | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/mmc/allwinner,sun4i-a10-mmc.= yaml b/Documentation/devicetree/bindings/mmc/allwinner,sun4i-a10-mmc.yaml index 9f3b1edacaa0..9e9610bb1eda 100644 --- a/Documentation/devicetree/bindings/mmc/allwinner,sun4i-a10-mmc.yaml +++ b/Documentation/devicetree/bindings/mmc/allwinner,sun4i-a10-mmc.yaml @@ -56,7 +56,9 @@ properties: - const: allwinner,sun50i-h616-mmc - const: allwinner,sun50i-a100-mmc - items: - - const: allwinner,sun55i-a523-mmc + - enum: + - allwinner,sun55i-a523-mmc + - allwinner,sun60i-a733-mmc - const: allwinner,sun20i-d1-mmc =20 reg: --- base-commit: dc59e4fea9d83f03bad6bddf3fa2e52491777482 change-id: 20260731-allwinner-a733-mmc-support-c901bc312eef Best regards, -- =20 Jerome
