This patch modifies pin control groups of SD pins on Exynos4210 and
Exynos4x12 to use drive strength 3, which corresponds to
S5P_GPIO_DRVSTR_LV4 in legacy non-DT code.
This is needed at least on Origen board for sdhci2 to work.

Well, the value of drive strength depends on board not SoC. So if required,
it should be moved to board DT stuff.
BTW, we can use the value as a default...I need to think about that again
for exynos4210 and 4x12.
Thanks.

Yes, I fully agree.
I've been thinking whether to change the defaults or just override them
for Origen, but I came to a conclusion that 3 (LV4) was the default in
non-DT code, so it probably should be also the default in DT variant.

I wonder which default value is more appropriate, 0 or 3?

In this case, yes, '3' is more useful...so can you re-submit this patch with
editing commit?
Thanks.

I can resubmit this patch, but I'm not sure what you expect me to edit.
Could you explain?
If possible, it would be nice to get this included in 3.8 as it's required
for Origen board to boot with device tree.

Hmm, I mean the commit message needs explanation is why to use '3' as a
default value is more useful. OK, if you don't mind, I will edit it when I
apply.

OK, as we discussed, I agree with this.
Will apply, thanks.
