Subject: Re: [PATCH net-next v5 0/5] net: phy: add Lynx PCS MDIO module

From: Ioana Ciornei <>
Date: Sun, 30 Aug 2020 11:33:57 +0300

> Add support for the Lynx PCS as a separate module in drivers/net/phy/.
> The advantage of this structure is that multiple ethernet or switch
> drivers used on NXP hardware (ENETC, Seville, Felix DSA switch etc) can
> share the same implementation of PCS configuration and runtime
> management.
> The module implements phylink_pcs_ops and exports a phylink_pcs
> (incorporated into a lynx_pcs) which can be directly passed to phylink
> through phylink_pcs_set.
> The first 3 patches add some missing pieces in phylink and the locked
> mdiobus write accessor. Next, the Lynx PCS MDIO module is added as a
> standalone module. The majority of the code is extracted from the Felix
> DSA driver. The last patch makes the necessary changes in the Felix and
> Seville drivers in order to use the new common PCS implementation.
> At the moment, USXGMII (only with in-band AN), SGMII, QSGMII (with and
> without in-band AN) and 2500Base-X (only w/o in-band AN) are supported
> by the Lynx PCS MDIO module since these were also supported by Felix and
> no functional change is intended at this time.

Series applied, thanks.
