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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

We already have a standard property for this. Use it.
