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.

v7->v8
- Rebased the changes on net-next
- Fixed return value in renesas_gbeth_init()

v6->v7
- Rebased the changes on net-next
- Added Reviewed-by tag from Russell
- Folded contenets of renesas_gbeth_clks_config()
  in renesas_gbeth_init/exit() as suggested by Philipp
- Dropped regs member from struct renesas_gbeth

v5->v6
- stmmac_pltfr_find_clk() is now used to find the clocks
- devm_stmmac_pltfr_probe() is now used to probe the platform device
  and dropped remove callback
- Switched to using init/exit callback to configure the clock
  instead of using the clks_config callback
- Dropped pm callback
- Fixed checkpatch warnings
- Added a new patch to update the MAINTAINERS file

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:

Cheers,
