Add in v1:
Can merge, but the function depend on the patch:

Please send me dts patch only after the driver part gets applied.

Ok, I will resend the patch after the driver part gets applied.
I just only want to speed up my upstream.

What is this property?  I cannot find it in any bindings doc.  Is it added by your
patches on driver code?

Sorry, it's the legacy property, after the latest discussion we will remove this property.
So I will remove it in the next version.
Thanks for your review.

Yuan Yao.
