Hi All,
We are working on bringing up ptp4l on Marvell CN9130 ARM Platform.
As a first step we are trying SW timestamp. But, hit the problem in
clock_create() function.
Clock is not getting created. But ethtool provides the SW timestamping
capability SOF_TIMESTAMPING_SOFTWARE is enabled.
Any patch or IOCTL missed? Any modification in kernel driver required?
Logs for reference:
