Please don't do that, don't change the meaning of already defined
clock identifiers. We should carefully assign the clock identifiers
based on the SoC documentation beforehand, not at will when we see
fit for development of the Linux driver. Please either add
DOUT_ACLK_CCORE_133 at the end of list or move this change to the
first patch in your series adding initial support for Exynos7 SoC.

Thanks for reviewing this series and picking up the initial patchset.
I will re-post this patchset with the ccore clock at the end of the
list. All the future clock id entries will be added at the bottom of
the list.

Please use mmc_hs200-1_8v instead.

As per synopsys-dw-mshc DT binding documentation, supports-highspeed
property is deprecated, so please use common DT binding for this,
which is "cap-mmc-highspeed".

I guess you mean "mmc-hs200-1_8v" (with a hyphen between mmc and hs200).

Above you suggest "cap-mmc-highspeed" to replace the same deprecated
property, but here "cap-sd-highspeed". What is the rationale behind
using only one particular new property and not both for both controllers?

Yes, right, that was a typo. Thanks.

Well, on this particular board dw_mmc channels are dedicated to use
only one kind of card. e.g. mmc_0 is for eMMC and which is
non-removable and mmc_2 is for SD cards. Although controller supports
both the properties on all channel on this SoC.

Will modify it to "mmc-hs200-1_8v".

Will use "cap-sd/mmc-highspeed" instead of "supports-highspeed".
