Does it means Serial Interface of SD, if yes. I've been added sdio0
for the same.
&sdio0 {
bus-width = <4>;
disable-wp;
non-removable;
pinctrl-names = "default";
pinctrl-0 = <&sdio0_bus4>, <&sdio0_cmd>, <&sdio0_clk>;
vmmc-supply = <&vcc_wl>;
vqmmc-supply = <&vccio_wl>;
status = "okay";
};

For UHS switch I've added vqmmc-supply
vccio_sd: vccio-sd-regulator {
compatible = "regulator-fixed";
regulator-name = "vccio_sd";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
vin-supply = <&vcc_io>;
};
And the slot detecting still 50MHz and timeout still effecting.
