Thanks for looking into this.

Yes, this patch is being tested on exynos7 platform which is ongoing
development.
The above link is one of them.
I feel this patch is too generic in nature and we now known at least
exynos7 is going to use this.
I don't know if there are any other ARM64 platform with dw_mmc controller.

So, I am going to leave this upto you to decide when to take this
patch, incase you decided to take it after exynos7 support lands, I
will send a reminder for this.
