AM6442: Does CPTS rely on any peripheral?

Part Number: AM6442

Tool/software:

Hi 

Customer met a issue on their own board and want to check with TI.

Phenomenon:

After the network port card is unplugged and the board is powered on, there is no /dev/ptp1 device.
Plug in the network port card and the device is started, there is a /dev/ptp1 device.


Purpose:

Whether there is a phy card or not, the /dev/ptp1 device is required.

Question:
Does the CPTS of cpsw depend on other peripherals of CPSW, and can it be used independently?
If it can be used independently, what should to do to enable this? If not, please explain why?

Regards

Zekun
