Subject: [PATCH] ARM: dts: Remove vmmc-supply for mmc@12220000 on arndale-octa board
Date: Fri, 25 Apr 2014 21:11:12 +0100 [thread overview]
Message-ID: <1398456672-3936-1-git-send-email-javi.merino@arm.com> (raw)
d726ca2d3316 (ARM: dts: Add vmmc-supply to MMC on arndale-octa board)
added the vmmc-supply to nodes mmc@12200000 and mmc@12220000 of the
DT. 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.

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.
Cheers,
Javi
