I do not know wheher other SoC need to use the optional properties as
abover. So here the name of the optional properties has "hi3660".


They should not have "hi3660" in their names either way, independent
of where they are used.


Oh, change the "hi3660" to "hisilicon"?
e.g. ufs-hi3660-use-rate-B --> ufs-hisilicon-use-rate-B

No, just 'use-rate-B', no prefix for this.

(note: this is different from the value of the "compatible" property
that
is meant to be as specific as possible".

Also, please clarify how your binding relates to the ufshcd binding
in Documentation/devicetree/bindings/ufs/ufshcd-pltfrm.txt: does
hi3660 implement any registers that are shared with ufshcd, or does
it use the same physical interface with a different register set?


No, only show how to use the dt-binding for hi3660 SoC


My question was about the hardware: does hi3660 implement ufshcd
or not?


YES

Ok, then the properties should be documented as optional in the
Documentation/devicetree/bindings/ufs/ufshcd-pltfrm.txt file for anything
that has a proper interpretation in the context of the generic ufshcd
driver.

OK I will modify this and update the patch soon.
