    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.
