Alex Elder 495787a792 greybus: tracing: add timing traces ... Bryan reports he used certain message traces to determine when time sync messages transit the boundary between the Greybus core and the host device. This patch adds two trace events--one a message event for outbound messages (because it indicates its operation and its destination), and one host device event for incoming messages (because message information isn't available as early as desired). These events are being created to allow the same sort of analysis of messages without having to store extra information for every message trace. (The next patch changes the information a message trace records.)
