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

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, Felix DSA switch etc) can share the
same implementation of PCS configuration and runtime management.

The PCS is represented as a mdio_device and the callbacks exported are
highly tied with PHYLINK and can't be used without it.

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
driver in order to use the new common PCS implementation.

At the moment, USXGMII (only with in-band AN and speeds up to 2500),
SGMII, QSGMII 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
funtional change is intended at this time.

Ioana Ciornei (4):
  net: phylink: consider QSGMII interface mode in
  net: mdiobus: add clause 45 mdiobus write accessor
  net: phy: add Lynx PCS MDIO module
  net: dsa: felix: use the Lynx PCS helpers

Russell King (1):
  net: phylink: add interface to configure clause 22 PCS PHY
