ptp: support ptp physical/virtual clocks conversion
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.
