Re: [PATCH net-next 1/1] stmmac: intel: Separate ADL-N and RPL-P device ID from TGL

Re: [PATCH net-next 1/1] stmmac: intel: Separate ADL-N and RPL-P device ID from TGL

[Vee Khee Wong]

What is the purpose of this patch?

The function definition looks exactly the same as ‘tgl_sgmii_phy0_data’.

[Sit, Michael Wei Hong]

This is to allow finer control on platform specific features for ADL and RPL.
There are some features that ADL and RPL doesn’t support and TGL supports vice versa.

Michael

But if they are the same _right_ _now_ what's the point?
Please repost as part of a series which actually modifies
the contents.

Please remember not to top post on the ML.

Noted. Thanks Vee Khee and Jakub for the comments. There is some work in progress as part of ADL-N development. We'll submit a complete patchset when it is completed in the future. Let's close the review for this patch for now.
