Stephen, In the current driver code, there is a substring comparison for "mdp" in device node name as part of probe sequence. If "mdp" is not present in the node name, it will return an error resulting in probe failure. Can we continue using mdp as nodename instead of display controller?
Can we fix the driver to not look for node names and look for compatible strings instead? It took me a minute to find compare_name_mdp() in drivers/gpu/drm/msm/msm_drv.c to understand what you're talking about. Perhaps looking for qcom,mdp5 in there will be sufficient instead of looking at the node name.
Sure Stephen. I will make the necessary changes in msm_drv.c to look for compatible string instead of node name. Can I include these two changes (changing mdp--> display controller and msm_drv.c changes) in a separate series ?
Thanks, Krishna
