Hello team,
I had no issue with using software time stamping and also I am able to see
the hardware timestamping support by building new kernel. But when I try to
use the PHC, I see the PHC clock not being updated correctly. I see only
the nSec bits being updated. Here are some of the tests I did.

Hello Miroslav, thanks for your reply. I am using Microchip SAMA7G54, it is
an arm cortex A7-based MPU and it does have a PTP time stamping unit at the
MAC layer.
Enabled the hardware PTP support in the kernel by adding
MACB_CAPS_GEM_HAS_PTP and CONFIG_MACB_USE_HWTIMESTAMP.

Hello Jacob,
Thanks for your reply. Yes, I can use the phc_ctl set and I see the phc
being updated to the current time of the day. If I try phc get, again I see
only the nSec bits being updated. Looks like it is something to do with the
drivers.
