media: cros-ec-cec: Get number of CEC ports from EC

2023-09-27T07:39:55Z

Add a new CEC port count host command and use it to query the number of CEC ports from the EC. If the host command is not supported then it must be old EC firmware which only supports one port, so fall back to assuming one port. This patch completes support for multiple ports in cros-ec-cec.

media: cros-ec-cec: Support receiving messages from multiple ports

2023-09-27T07:39:54Z

Currently, received messages are sent from the EC in the cec_message MKBP event. Since the size of ec_response_get_next_data_v1 is 16 bytes, which is also the maximum size of a CEC message, there is no space to add a port parameter. Increasing the size of ec_response_get_next_data_v1 is an option, but this would increase EC-kernel traffic for all MKBP event types. Instead, use an event to notify that data is ready, and add a new read command to read the data. For backwards compatibility with old EC firmware, continue to handle cec_message events as well.
