The switch has two controllable I/Os which are usually connected to LEDs. This
is useful to immediately visually see the PTP status.
These provide two signals:
* is_gm
This LED can be activated if the current device is the grand master in that
PTP domain.
* sync_good
This LED can be activated if the current device is in sync with the network
time.
Expose these via the LED framework to be controlled via user space
e.g. linuxptp.

subsystem, nonetheless:
