Hi, Ulf. If we know whether card is eMMC or SD, then just use only cap-mmc-highspeed or cap-sd-highspeed, isn't? In exynos series's case, i know the card is eMMC or SD, so use one of them. But i didn't know whether card is eMMC or SD at other SoC, so added all property. Do you think it need to add all property? snip[...] >> }; >> >> mmc@12220000 { >> num-slots = <1>; >> - supports-highspeed; >> card-detect-delay = <200>; >> samsung,dw-mshc-ciu-div = <3>; >> samsung,dw-mshc-sdr-timing = <2 3>; >> samsung,dw-mshc-ddr-timing = <1 2>; >> pinctrl-names = "default"; >> pinctrl-0 = <&sd2_clk &sd2_cmd &sd2_cd &sd2_bus4>; >> - >> - slot@0 { >> - reg = <0>; >> - bus-width = <4>; >> - wp-gpios = <&gpc2 1 0>; >> - }; >> + bus-width = <4>; >> + wp-gpios = <&gpc2 1 0>; > > cap-sd-highspeed? > cap-mmc-highspeed?

dw-mmc controller can support multiple slots. But, there are no use-cases anywhere. So we don't need to support the slot-node for dw-mmc controller.
