The Ethernet driver use phy-handle to reference the PCS/PMA PHY. This could be a problem if one wants to configure an external PHY via phylink, since it use the same phandle to get the PHY. To fix this, introduce a dedicated pcs-handle to point to the PCS/PMA PHY and deprecate the use of pointing it with phy-handle. A similar use case of pcs-handle can be seen on dpaa2 as well. --- patch v5 --- - Re-applying the v4 patch on the net tree. - Describes the pcs-handle DT binding at ethernet-controller level. --- patch v6 --- - Remove "preferrably" to clearify usage of pcs_handle.
