This patch is a preparation patch. On the subsequent patches[1] [2] and [3] you will see the real hw changes wr.to gen2/gen3. Feature bit is not added in this patch, but on the subsequent patches. I believe you haven't reviewed that patches yet.

PTP feature and the diff between gen2/gen3
------------------------------------------
[1] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20210722141351.13668-7-biju.das.jz@bp.renesas.com/


Features specific to R-Car Gen3
--------------------------------
[2] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20210722141351.13668-8-biju.das.jz@bp.renesas.com/


R-Car common features
---------------------

[3] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20210722141351.13668-9-biju.das.jz@bp.renesas.com/

There is a review comment for making smaller changes. 
what do you recommend after going through [1],[2] and [3]. 
Please let us know.

Regards,
Biju
