Thanks Rob for reviews.
We are using Display Port Controller block to detect hot plug.
So we won't be using that pin as GPIO.
I found now that we don't need any bindings for that pin in such case.
So I am abandoning this patch series and upload new patch.
Thanks.

Add Display Port HPD GPIO description in bindings
This Patch depends on:
https://patchwork.kernel.org/patch/11468505/
This belongs below the '---' and probably means you should send all
this
as one series.
