No driver update should be required for HS400, see below. > Signed-off-by: Wolfram Sang <[email protected]> > --- > > Note: we shouldn't enable HS400 in the DTS files yet, since we don't have the > 8 > tap support. But I think we can enable basic support. 8 tap support is included in the following patch which was accepted for inclusion in upstream (search for 4TAP): 26eb2607fa28 ("mmc: renesas_sdhi: add eMMC HS400 mode support") > Documentation/devicetree/bindings/mmc/tmio_mmc.txt | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/Documentation/devicetree/bindings/mmc/tmio_mmc.txt > b/Documentation/devicetree/bindings/mmc/tmio_mmc.txt > index 839f469f4525..c434200d19d5 100644 > --- a/Documentation/devicetree/bindings/mmc/tmio_mmc.txt > +++ b/Documentation/devicetree/bindings/mmc/tmio_mmc.txt > @@ -28,6 +28,7 @@ Required properties: > "renesas,sdhi-r8a7796" - SDHI IP on R8A7796 SoC > "renesas,sdhi-r8a77965" - SDHI IP on R8A77965 SoC > "renesas,sdhi-r8a77980" - SDHI IP on R8A77980 SoC > + "renesas,sdhi-r8a77990" - SDHI IP on R8A77990 SoC > "renesas,sdhi-r8a77995" - SDHI IP on R8A77995 SoC > "renesas,sdhi-shmobile" - a generic sh-mobile SDHI controller > "renesas,rcar-gen1-sdhi" - a generic R-Car Gen1 SDHI controller > -- > 2.11.0 >
