So for mcbin, I have:

&ap_sdhci0 {
        bus-width = <8>;
        marvell,xenon-emmc;
        marvell,xenon-phy-type = "emmc 5.1 phy";
        /*
         * Not stable in HS modes - phy needs "more calibration", so add
         * the "slow-mode" and disable SDR104, SDR50 and DDR50 modes.
         */
        marvell,xenon-phy-slow-mode;
        no-1-8-v;
        non-removable;
        status = "okay";
        vqmmc-supply = <&v_vddo_h>;

        #address-cells = <1>;
        #size-cells = <0>;
        mmccard: mmccard@0 {
                compatible = "mmc-card";
                reg = <0>;
        };
};

Does this mean the "mmccard" bit is no longer required - or is it required
for the eMMC to be detected but is no longer supported by the driver?

Thanks.
