[PATCH] ARM: dts: Remove vmmc-supply for mmc@12220000 on arndale-octa board
d726ca2d3316 (ARM: dts: Add vmmc-supply to MMC on arndale-octa board)
added the vmmc-supply to nodes mmc@1220 and mmc@1222 of the
DT. However, this makes the kernel fail to boot on the arndale-octa
spews:
[5.06] dwmmc_exynos 1220.mmc: num-slots property not found,
assuming 1 slot is available
[5.065000] platform 1220.mmc: Driver dwmmc_exynos requests probe
deferral
[5.075000] dwmmc_exynos 1222.mmc: num-slots property not found,
assuming 1 slot is available
[5.085000] platform 1222.mmc: Driver dwmmc_exynos requests probe
deferral
And eventually hangs. Without the vmmc-supply property in the
mmc@1222 node, the kernel boots again.

Hi,

is that 3.15-rc2 fails to boot on my Arndale Octa unless I apply this
