| | | | | | | | | | | | | | | | | | | | | | | This allows the implementation of bb_retimer_power_handle() to return a status value indicating whether the request was successful. The default implementation simply controls a GPIO and is expected to succeed unconditionally. More complex implementations may run into failure cases that leave the BB unreachable. When this happens, device initialization returns an error so the caller can take mitigating action. USB MUX operations tend to be called from timing sensitive code paths in the TCPM, so careful error handling helps avoid cascading problems like PD negotiation failures.
