qca8081 supports IEEE1588 feature, the IEEE1588 code may be submitted in

so it may be a good idea to keep it out from at803x code.
The AR8031 also supports PTP. Unfortunately, there is no public datasheet
for the QCA8081, so I can't have a look if both are similar.

Hi Michael,

Thanks for this comment. it is true that AR8031 supports basic PTP features.

please refer to the following link for the outline features of qca801.

https://www.qualcomm.com/products/qca8081
Is the PTP hardware in the qca8081 the same as the ar8031? When you
add PTP support, will it be for both PHYs?

What about the cable diagnostics? The at803x already has this
implemented. Will the same work for the qca8081?

Hi Andrew,

qca8081 enhances the ptp feature from AR8031, the new ptp driver should be for qca8081, which is fully

tested on qca8081, but it is not verified on AR8031 currently.

the cable diagnostics feature of qca8081 is almost same as ar8031 but the register is changed, will correct it

for qca8081 in the next patch correspondingly.

thanks.
