No, it belongs to the "of the box", not to "PPS".  The kernel for the
tinkerboard has PPS support (core) compiled in, but the device
configuration doesn't allow it to be used: the three UARTs that should
work with PPS line discipline are shadowed by the GPIO ports and there
is no pps-gpio module or device to connect to as an alternative.
Although PPS out actually is a possibility there is a PPS echo device
(that must be optionally configured) that you could connect to some GPIO
and then figure out the internal delay and jitter from that via a TDC.

Achim.
