After pull the merge of 3.13-rc1, the dw_mmc-exynos will make the boot
stock.In 3.13, it is just stocked udev in 3.13 and makse udev timeout
but kernel report the emmc device is found.
And in the Documentation/devicetree/bindings/mmc/exynos-dw-mshc.txt I
saw that it is need to define which gpio ports that a emmc slot use,
but when I watched others dts, they use pinctrl, which is correct?
Here is the log and dts

Looks like a clock issue on 4412? I only have 5250 that I boot test
on, no EXYNOS4 coverage at all (I had an Odroid-X but it wasn't useful
due to the very old u-boot it came with so I gave it away).
Tomasz, is this something you can reproduce on 4210/4412?

Thank you for detect.
Clock adaptation has been added for upper host including EXYNOS 5250
since c6d9d(mmc: dw_mmc: exynos: adjust the clock rate with speed mode)
It should have been considered for all EXYNOS.
I could send a fix.
Thanks,

yes, may c6d9deda64d426a25aafeb179962c9cf3c834e2f cause problem.
Actually, my u-boot is old too(modified from samsung BSP, it is
2010.12), I use CONFIG_ARM_APPENDED_DTB to use dts.

Nope. All of our boards (exynos4210-trats, exynos4412-trats2) are
configured to use sdhci-s3c for all MMC slots[1], as at the time they got
submitted to mainline, this driver was considered more reliable than
dw-mmc. Not sure about today, though.
[1] On Exynos4 there is one dw-mmc block and four sdhci-s3c blocks,
while there are just four physical busses. Using pin control you can
configure any of the four sets of pins to work either using its dedicated
sdhci-s3c or the only one dw-mmc.
Best regards,
Tomasz

Well I don't think it can work this time, maybe my dts is wrong.
At this time neither emmc nor usb can work.

Hi, Randy,
It seems a problem that controller didn't find the clock source.
Also you can see the below message. Did you check the clock source?
> [ 1.125000] s3c-sdhci 12550000.sdhci: failed to get io clock
Actually, need to prevent the "null pointer dereference" for clock in dw-mmc.c
And If dw-mmc controller can be used, recommend to use it.
dw-mmc can use DDR mode, but sdhci can't.
Best Regards,
Jaehoon Chung

Thanks Jaehoon,
I have noticed that before it, but in dw_mmc driver, I won't meet this
problem.
As you can seen in dts, I have defined a clock source.
Or the clock source what I choose is not correct?
I don't know how to debug this, I don't know much about it.
Actually, I don't really understand the contain in chapter 7 of datasheet.
I am sorry for that.
Would you like to tell me some more about it?

Thanks Jaehoon,
I have noticed that before it, but in dw_mmc driver, I won't meet this
problem.
As you can seen in dts, I have defined a clock source.
Or the clock source what I choose is not correct?
I don't know how to debug this, I don't know much about it.
Actually, I don't really understand the contain in chapter 7 of datasheet.
I am sorry for that.
Would you like to tell me some more about it?

Can you add the followings for you test?
