No worries, thanks for digging in. I'll get my branch back up and rebase on top of this and resume from there. I can't remember all the details right now - so it will be interesting to see how to handle the issues you've mentioned above - but I think some of it is what I was trying to work on. (dealing with getting the BPC at least..., so I don't know if I considered the issue you reference about case of the driver not creating a connector). I don't think I'll be able to resume my DRM work for more than a couple of weeks now though so I'm going to be a bit longer. Hopefully your patch here looks like it could be merged independently though. -- Kieran > > Sorry if this is a duplicate - something went wrong when I sent this > mail the first time. > > Sam > > > Sam Ravnborg (1): > drm/bridge: ti-sn65dsi86: Use atomic variants of drm_bridge_funcs > > drivers/gpu/drm/bridge/ti-sn65dsi86.c | 23 +++++++++++++++-------- > 1 file changed, 15 insertions(+), 8 deletions(-) > >
