Hi Hans, I'm writing to you in order to get more details about current CEC implementation status. I've seen the code and it appears you have already support for CEC 2.0, right? I've also seen the implementation in adv7511 of CEC and I've extracted the following sequence: 1) Call cec_allocate_adapter with given flags and given cec_adap_ops (enable, log_addr, transmit, ...) 2) Call cec_register_adapter when all datapath is configured 3) Call cec_received_msg when a msg is received Is there anything missing? Can you please confirm that these are the essential points in order to implement CEC? And about userspace: It should implement the logic of formating and the following the messages to cec core, right? Does cec-ctl utility and cec-funcs.h already handles CEC 2.0? Thank you in advance for your help. With best regards, Jose Miguel Abreu
