I don't think we should merge this as-is. This patch also seems dependent on patch 1 of the series. Shouldn't they be merged together (please don't merge them as-is, though)?

I don't think we should merge this as-is. Yeah, I have floated the IGT changes to support this series: https://patchwork.freedesktop.org/series/102387/ With this IGT change, we can merge this series as-is. I would like to request you to review IGT patches too. > > This patch also seems dependent on patch 1 of the series. Shouldn't > they be merged together (please don't merge them as-is, though)? Yes, as other patches in this series are already reviewed, I think we need to plan to merge all patches in this series together (If above IGT & this patch looks good to you). - Bhanu > > Harry > >> - Bhanu >> >>> >>> Thanks and Regards, >>> Arun R Murthy >>> -------------------- >>

As drm_connector already have the display_info, instead of creating "output_bpc" debugfs in vendor specific driver, move the logic to the drm layer. This patch will also move "Current" bpc to the crtc debugfs from connector debugfs, since we are getting this info from crtc_state.
