From: Biju Das <biju.das.jz@bp.renesas.com> Compared to other Renesas GBETH stmmac glue drivers, RZ/G3L GBETH IP use the version Synopsys DesignWare MAC (version 5.30). It has an extra clock compared to RZ/V2H and has ptp_pps_o interrupts. Add support for RZ/G3L GBETH by reusing device data of RZ/V2H and can be extended to add other functionalities later.
