Hi,

Thank you for your reply.

How can I check the supported version?

Is the support version of the following driver Linux 5.10 not 5.15.x?

Hi Atsushi,

The only version we test on is Linux 5.10 internally for all the PHY. We did not test the file with other version so that we cannot tell rather it support Linux 5.15x as well.

Hi,

Sorry for the late reply.

Does the latest version support previous version?

Specifically, is the Linux 5.10 driver able to be used with versions prior to Linux 5.9?

Hi Atsushi,

I am not sure on this Linux comment. Are you able to try it out on your side to see rather it can run Linux 5.5?

Hi,

Thank you for your reply.

I checked with the customer, it seems that this driver is not available for Linux 5.4.x because there was major changes after Linux 5.4.x.

Is it possible to provide the old driver for Linux 5.4.x?

Or do you have any solution?

Hi Atsushi,

Sorry we only have the Linux 5.10 version.
