PS1, Line 10: In
            : particular, this allows depthcharge to control the state of an
            : external USB mux. Some SoCs like Tiger Lake have a USB mux for Type-C
            : ports that must be kept in sync with the state of the port as reported
            : by the TCPC. This can be achieved by hookink into the poll routine to
            : refresh the state of the USB mux.
This explains the problem to solve. But not why it's done in
depthcharge instead of libpayload?
