The crc16() function is used to check the firmware validity, but
the library was not explicitly selected.

ptp: ocp: Add firmware header checks

2022-05-24T18:39:54+00:00

Right now it's possible to flash any kind of binary via devlink and
break the card easily. This diff adds an optional header check when
installing the firmware.

ptp: ocp: fix PPS source selector debugfs reporting

2022-05-24T18:39:54+00:00

The NTL timecard design has a PPS1 selector which selects the
the PPS source automatically, according to Section 1.9 of the
documentation.

  If there is a SMA PPS input detected:
     - send signal to MAC and PPS slave selector.

  If there is a MAC PPS input detected:
     - send GNSS1 to the MAC
     - send MAC to the PPS slave

  If there is a GNSS1 input detected:
     - send GNSS1 to the MAC
     - send GNSS1 to the PPS slave.MAC

Change the debugfs summary so it reflects the correct mapping,
for assistance in debugging.  No functional change.

ptp: ocp: add .init function for sma_op vector

2022-05-24T18:39:54+00:00

Create an .init function for the op vector, and a corresponding
wrapper function, for different sma mapping setups.

Add a default_fcn to the sma information, and use it when displaying
information for pins which have fixed functions.
