net: phy: add Lynx PCS module Add a Lynx PCS module which exposes the necessary operations to drive the PCS using phylink. The majority of the code is extracted from the Felix DSA driver, which will be also modified in a later patch, and exposed as a separate module for code reusability purposes. As such, this aims at feature and bug parity with the existing Felix DSA driver, and thus USXGMII, SGMII, QSGMII and 2500Base-X (only w/o in-band AN) are supported by the Lynx PCS module since these were also supported by Felix. The module can only be enabled by the drivers in need and not user selectable. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S.

net: pcs: lynx: add lynx_pcs_create_mdiodev() Add lynx_pcs_create_mdiodev() to simplify the creation of the mdio device associated with lynx PCS. In order to allow lynx_pcs_destroy() to clean this up, we need to arrange for lynx_pcs_create() to take a refcount on the mdiodev, and lynx_pcs_destroy() to put it. Adding the refcounting to lynx_pcs_create()..lynx_pcs_destroy() will be transparent to existing users of these interfaces.
