I'm pretty sure we've discussed it before, but can you make this so that the generic properties are part of the ufshcd binding, and you refer to it from here, only describing in what ways the hisi ufs binding differs from the standard?

The clock names sound generic enough, should we have both in the generic binding?
"ref_clk" is in the ufshcd-pltfrm binding, but "phy_clk" is not; what do you mean is that these two don't need to document here?
> +- resets : reset node register, one reset the clk and the other reset the controller
> +- reset-names : describe reset node register
This looks incomplete. What is the name of the reset line supposed to be?
I'd also suggest you document it in the ufshcd binding instead.
As discussed in https://lkml.org/lkml/2017/11/30/1077;
If document it in the ufshcd binding, I think it needs some codes to parse them in ufshcd.c/ufshcd-pltfrm.c, but I think these codes may not be applicable to other SOC manufacturers.
