The bananapi-r2 board has an SD-card controller, enable the device in the devicetree.

I can base the patch to fixup and add something in the next version
such as
1) to add property with extra wp-gpios
2) to correct power source from mt6323_vio18_reg instead of
mt6323_vmc_reg based on the schematic
3) to enable mmc0 that is used as emmc
&mmc0 {
pinctrl-names = "default", "state_uhs";
pinctrl-0 = <&mmc0_pins_default>;
pinctrl-1 = <&mmc0_pins_uhs>;
status = "okay";
bus-width = <8>;
max-frequency = <50000000>;
cap-mmc-highspeed;
vmmc-supply = <&mt6323_vemc3v3_reg>;
vqmmc-supply = <&mt6323_vio18_reg>;
non-removable;
};
&mmc1 {
pinctrl-names = "default", "state_uhs";
pinctrl-0 = <&mmc1_pins_default>;
pinctrl-1 = <&mmc1_pins_uhs>;
status = "okay";
bus-width = <4>;
max-frequency = <50000000>;
cap-sd-highspeed;
cd-gpios = <&pio 261 0>;
wp-gpios = <&pio 29 0>;
vmmc-supply = <&mt6323_vmch_reg>;
vqmmc-supply = <&mt6323_vio18_reg>;
};
those upper nodes could make sdhc sd card/emmc workable
