[PATCH 6.1.y-cip 0/9] Add RZ/V2H GBETH support

[PATCH 6.1.y-cip 0/9] Add RZ/V2H GBETH support

[Ovidiu Panait]

Hi,

This patch series adds GBETH support for the Renesas RZ/V2H SoC,
to the linux-6.1.y-cip kernel.

Patches were cherry-picked from mainline kernel.

Note: this series depends on the following RZ/G3E series:
https://lore.kernel.org/cip-dev/20251103113608.36240-1-john.madieu.xa@bp.renesas.com/

Best regards,
Ovidiu

[PATCH 6.1.y-cip 3/9] clk: renesas: r9a09g057: Add clock and reset entries for GBETH0/1

[Ovidiu Panait]

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

commit 598b2a06702c12916d97640dbfb09bfdbf002c5c upstream.

Add clock and reset entries for GBETH instances. Include core clocks for
PTP, sourced from PLLETH, and add PLLs, dividers, and static mux clocks
used as clock sources for the GBETH IP.

[PATCH 6.1.y-cip 4/9] dt-bindings: net: Define interrupt constraints for DWMAC vendor bindings

[Ovidiu Panait]

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

commit 5a1dddd2944492edb1e61c5db1cc386e5419fcf4 upstream.

The `snps,dwmac.yaml` binding currently sets `maxItems: 3` for the
`interrupts` and `interrupt-names` properties, but vendor bindings
selecting `snps,dwmac.yaml` do not impose these limits.

Define constraints for `interrupts` and `interrupt-names` properties in
various DWMAC vendor bindings to ensure proper validation and consistency.

[PATCH 6.1.y-cip 5/9] dt-bindings: net: dwmac: Increase 'maxItems' for 'interrupts' and 'interrupt-names'

[Ovidiu Panait]

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

commit 8c989368c04c17a6ed834ae528458844f553bead upstream.

Increase the `maxItems` value for the `interrupts` and `interrupt-names`
properties to 11 to support additional per-channel Tx/Rx completion
interrupts on the Renesas RZ/V2H(P) SoC, which features the
`snps,dwmac-5.20` IP.

Refactor the `interrupt-names` property by replacing repeated `enum`
entries with a `oneOf` list. Add support for per-channel receive and
transmit completion interrupts using regex patterns.

[PATCH 6.1.y-cip 6/9] arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Replace RZG2L macros

[Ovidiu Panait]

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

commit 6e526427fa78439cc8045068d78df1d8cd911213 upstream.

Replace RZG2L_* macros with RZV2H_* macros, so that we can define
port names in alpha-numeric.

[PATCH 6.1.y-cip 9/9] arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Fix pinctrl node name for GBETH1

[Ovidiu Panait]

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

commit ffcc8c2e97ca29494687201557fd984d16d5cc4c upstream.

Rename the GBETH1 pinctrl node from "eth0" to "eth1" to avoid duplicate
node names in the DT and correctly reflect the label "eth1_pins".

This series looks ok to me. I can apply it if it passes testing and if
there are no other comments.
