Re: [Freedreno] [PATCH 0/4] drm/msm/dp: Add support for SC8180x eDP controller

[abhinavk@codeaurora.org]

Hi Bjorn

I had a quick glance on the series and before getting to other things 
wanted to know how you are initializing two different connectors for
DP & EDP resp.

The connector type for DP should be DRM_MODE_CONNECTOR_DisplayPort and 
eDP should be DRM_MODE_CONNECTOR_eDP.
We need both to be created so that both EDP and DP can be supported 
concurrently.

Will these changes work for concurrent eDP and DP case?

Thanks

Abhinav
