I'll remove the 'broken-cd' property.

I'll fix it as following by using ldo12_reg: vmmc-supply = <&ldo12_reg>;

I'll fix it like rinato board to handle the ldo11/ldo12 as following: gpk0-2 is XMMC0CDN pin.
ldo11_reg: LDO11 { - /* VDD_MMC */ + /* VDD74 ~ VDD75 */ regulator-name = "VLDO11_1.8V"; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; - regulator-always-on; + samsung,ext-control-gpios = <&gpk0 2 GPIO_ACTIVE_HIGH>; };

OK. I'll merge it with 5/10 patch. Best Regards, Chanwoo Choi
