However, this makes the kernel fail to boot on the arndale-octa spews: [ 5.060000] dwmmc_exynos 12200000.mmc: num-slots property not found, assuming 1 slot is available [ 5.065000] platform 12200000.mmc: Driver dwmmc_exynos requests probe deferral [ 5.075000] dwmmc_exynos 12220000.mmc: num-slots property not found, assuming 1 slot is available [ 5.085000] platform 12220000.mmc: Driver dwmmc_exynos requests probe deferral And eventually hangs. Without the vmmc-supply property in the mmc@12220000 node, the kernel boots again. Signed-off-by: Javi Merino --- Hi, Note that I don't know *why* removing the property works, all I know is that 3.15-rc2 fails to boot on my Arndale Octa unless I apply this patch.
