[PATCH net-next v3 0/2] Add support for Renesas RZ/G3L GBETH

[PATCH net-next v3 0/2] Add support for Renesas RZ/G3L GBETH

[Biju]

From: Biju Das <biju.das.jz@bp.renesas.com>

The Renesas RZ/G3L GBETH IP uses Synopsys DesignWare MAC version 5.30
compared to other Renesas SoC such as RZ/V2H that use MAC version 5.20.

The RZ/G3L GBETH requires an extra clock compared to RZ/G3E and has pps
interrupts. Document the Renesas RZ/G3L GBETH IP in bindings and add
support for the RZ/G3L GBETH in dwmac-renesas-gbeth glue driver.

v2->v3:
 * Fixed the typo ppt->ptp as pointed by netdev-ai[1] in bindings
 * Keep the tag as the change is trivial.
 * Collected tag for the driver
v1->v2:
 * Separated ethernet patches from series [2]
 * Collected tag for binding patch

[PATCH net-next v3 2/2] net: stmmac: dwmac-renesas-gbeth: Add support for RZ/G3L SoC

[Biju]

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.
