Hi Conor, Thank you for your response. That's a fair point about the risk of the DRM approach being rejected. While I can't be certain, I'm hopeful that part is relatively straightforward, as it primarily integrates other recently reviewed (though not yet merged) components like the inno-hdmi bridge and dc8200 drivers. To be honest, I was more concerned that the DT part of the series would be more problematic. Given that, I would find it very helpful to get your feedback on the DT aspects now, if you have the time.
