[PATCH net-next 0/8] Add support for Renesas RZ/G3L GBETH

[PATCH net-next 0/8] 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 enable
the Gigabit Ethernet Interface (GBETH0) populated on the RZ/G3L SMARC
EVK. The eth1, pincontrol definitions and hotplug support will be added
later.

[PATCH net-next 1/8] dt-bindings: net: renesas,rzv2h-gbeth: Document Renesas RZ/G3L SoC

[Biju]

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

Add device tree binding support for the Gigabit Ethernet (GBETH) IP on
Renesas RZ/G3L SoC. This SoC uses different Synopsys DesignWare MAC
version 5.30 compared to RZ/G3E.

RZ/G3L requires an extra clock compared to RZ/G3E and has pps interrupts.

Add a new compatible string "renesas,r9a08g046-gbeth" for RZ/G3L SoC and
update the schema to handle hardware differences between SoC variants.

Extend the base snps,dwmac.yaml schema to accommodate the PPS interrupts.

[PATCH net-next 2/8] 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.

[PATCH net-next 8/8] arm64: dts: renesas: rzg3l-smarc-som: Enable eth0 (GBETH) interface

[Biju]

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

Enable the Gigabit Ethernet Interfaces (GBETH) populated on the RZ/G3L
SMARC EVK. The eth1, pincontrol definitions and hotplug support will be
added later.

Thanks for your series!

Please don't include "net-next" tags in patches that are not meant
to be applied to the net-next tree.
