Ah, right =). I'll drop that from the desc. Tomi
Hi Tomi, Thank you for the patch.

Wouldn't it be simpler and cleaner to add the connector type to the omap_dss_device structure ? That's more work though, so as a first step I think I could tolerate this hack if you really feel lazy ;-) Although, maybe we should just return SVIDEO unconditionally for VENC for now and fix that later. > + return DRM_MODE_CONNECTOR_Unknown; > + case OMAP_DISPLAY_TYPE_SDI: > + return DRM_MODE_CONNECTOR_LVDS; > default: > return DRM_MODE_CONNECTOR_Unknown; > }

Yes, it looks a bit ugly to me too. I've been reluctant to add more things to omap_dss_device and to the panel/encoder drivers, as I think each thing there will make it more difficult to convert driver the model to more DRM'ish model. So, I think I'll just use the SVIDEO as I had originally. Tomi

We have been using DRM_MODE_CONNECTOR_Unknown for many of our outputs because there has not been a proper connector type for them. We now have connector type for DPI so let's take it into use. At the same time, add better connector types for the remaining outputs too. This patch sets the following outputs to use the following connector types: DPI -> DPI DBI -> DPI (MIPI DBI is very similar to DPI at the bus level) SDI -> LVDS (SDI, TI Flatlink 3G, is a type of LVDS) VENC -> SVIDEO (it could also be composite, but we don't have that information here, so svideo should be quite good match) Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> --- drivers/gpu/drm/omapdrm/omap_drv.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
