Specific for your case, you just need add dtm and hdcp ta version in amdgpu_debugfs_firmware_info, Similar as xgmi and ras ta. The following cmd will give you all the firmware version information.
sudo cat /sys/kernel/debug/dri/x/amdgpu_firmware_info

Hold on please.
I don't think this is the best approach as we already had existing debugfs interface for that purpose. We shall centralize all the firmware information query under amdgpu_debugfs_firmware_info, and user should go through debugfs to query firmware information.
