ptp: Relocate lookup cookie to correct block.

2021-07-08T19:33:10+00:00

An earlier commit set the pps_lookup cookie, but the line
was somehow added to the wrong code block.  Correct this.

ptp: add kernel API ptp_get_vclocks_index()

2021-07-01T20:08:18+00:00

Add kernel API ptp_get_vclocks_index() to get all ptp
vclocks index on pclock.

This is preparation for supporting ptp vclocks info query
through ethtool.

ptp: support ptp physical/virtual clocks conversion

2021-07-01T20:08:18+00:00

Support ptp physical/virtual clocks conversion via sysfs.
There will be a new attribute n_vclocks under ptp physical
clock sysfs.

- In default, the value is 0 meaning only ptp physical clock
  is in use.
- Setting the value can create corresponding number of ptp
  virtual clocks to use. But current physical clock is guaranteed
  to stay free running.
- Setting the value back to 0 can delete virtual clocks and back
  use physical clock again.

Another new attribute max_vclocks control the maximum number of
ptp vclocks.

ptp: Set lookup cookie when creating a PTP PPS source.

2021-06-29T18:29:37+00:00

When creating a PTP device, the configuration block allows
creation of an associated PPS device.  However, there isn't
any way to associate the two devices after creation.

Set the PPS cookie, so pps_lookup_dev(ptp) performs correctly.

Trivial conflicts in net/can/isotp.c and
tools/testing/selftests/net/mptcp/mptcp_connect.sh

scaled_ppm_to_ppb() was moved from drivers/ptp/ptp_clock.c
to include/linux/ptp_clock_kernel.h in -next so re-apply
the fix there.
