Thanks Jaehoon, pulled into my next branch!
Reported by kernelci, It seems like some of these patches are causing
the exynos5250-arndale to fail to boot.
I looked briefly at the logs and the bisect report (which isn't
complete) and it turns out that the eMMC card at mmc0 isn't detected
properly.
Here's the boot summary (it turns out there are more boards failing,
don't know if all are related to dw_mmc, yet):
https://kernelci.org/boot/all/job/ulfh/kernel/v4.7-rc5-92-g4e01b578ade9/
I quickly look at the failed bootlogs of your reports.
My three patches don't touch the behaviour for which I search dw_mmc
code to find whether it will generate some possible to make mmc-core
got -EINVAL. It's a little difficult for me to point out the root cause
without more debug log or geting the real failed board.
It will be great if Jaehoon have a exynos5250-* board to debug?
Or Ulf, could you revert the commit 97f659a2e (mmc: dw_mmc: prevent to
set the wrong value) to see if we could boot up exynos5250-arndale
successfully?
Here's the bootlog:

Please, could any of you dw_mmc experts have a look at this as soon as
possible!?
Kind regards
Uffe
