Thank you to Konrad, Neil, and others for the very prompt and helpful reviews.
Based on the feedback received, I think it best to withdraw this series to address the issues raised, most notobly: 1. The DP_TRAIN_LEVEL_MAX change (patch 3) is too broad - it affects all devices using the Qualcomm MSM DP driver rather than being specific to the RA620 bridge. A proper fix should be implemented at the bridge level. This is going to take more investigation. 2. The display DT nodes (patch 5) should use the radxa,ra620 compatible string per the existing Radxa upstream series from Xilin Wu, and the lane ordering needs correcting. 3. The rpmh-rsc early return (patch 1) needs further review regarding the implications of returning before full driver initialization. 4. DTS patch label dependency issue (sorry) I'll integrate with the Radxa upstream effort, re-evaluate the other areas and resubmit corrected patches addressing these concerns at a later date. Thanks for the feedback. Cheers Graham
