Subject: [PATCH net-next v5 0/3] Add GBETH glue layer driver for Renesas RZ/V2H(P) SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series adds support for the GBETH (Gigabit Ethernet) glue layer
driver for the Renesas RZ/V2H(P) SoC. The GBETH IP is integrated with
the Synopsys DesignWare MAC (version 5.20). The changes include updating
the device tree bindings, documenting the GBETH bindings, and adding the
DWMAC glue layer for the Renesas GBETH.

v4->v5
- Rebased the changes on net-next

v3->v4
- Fixed maxItems for interrupt-names property
- Maintained reverse christmas tree order in renesas_gbeth_clks_config
- Returned err in case of success in renesas_gbeth_probe()

v2->v3
- Fixed review comments from Rob and Russell

v1->v2
- Updated commit description for patch 2/3
- Updated tx/rx queue completion interrupt names
- Added clks_config callback

v1:
https://lore.kernel.org/all/20250302181808.728734-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

Cheers,
Prabhakar
