Thanks for the patch, Morimoto-san.

I've now briefly tested this one on top of
renesas-devel-v3.14-rc1-20140207, and as long as the following Kconfig
entires are set then everything seems ok:

CONFIG_MMC_SDHI=y
CONFIG_REGULATOR_GPIO=y

I've tested boot-up and checking contents of /proc/partition and then
done a simple eject/insert test.

Not sure which ones that are appropriate:

Tested-by: Magnus Damm <damm@opensource.se>
Acked-by: Magnus Damm <damm@opensource.se>

Simon, can you please pick up this patch?

Thanks for your help.

Cheers,

/ magnus
