After pull the merge of 3.13-rc1, the dw_mmc-exynos will make the boot
stock.In 3.13, it is just stocked udev in 3.13 and makse udev timeout
but kernel report the emmc device is found.
And in the Documentation/devicetree/bindings/mmc/exynos-dw-mshc.txt I
saw that it is need to define which gpio ports that a emmc slot use,
but when I watched others dts, they use pinctrl, which is correct?
Here is the log and dts
