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.
