[..] On this note, does it perhaps make more sense to call the "internal" _dpu_encoder_phys_cmd_wait_for_idle function directly, instead of going through the "public" dpu_encoder_phys_cmd_wait_for_tx_complete which seems solely intended to handle the wait_for_tx_complete callback?
Either one would work. The main difference is the error message. Do you want to see it here if the wait times out or not?
I prefer calling _dpu_encoder_phys_cmd_wait_for_idle directly and optionally adding our own error message. IIRC DRM_ERROR prints source information such as the function this originated from, and that makes it impossible to distinguish between the wait_for_tx_complete callback or the invocation through dpu_encoder_phys_cmd_wait_for_commit_done anyway.
