[PATCH 1/2] dt-bindings: msm: disp: Add Display Port HPD GPIO bindings

[tanmay at codeaurora.org]

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.
