[PATCH 6.12-y.cip 1/5] clk: renesas: r9a09g056-cpg: Add clock and reset entries for GBETH0/1

[Ovidiu Panait]

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

commit bfb0bc6bdfdaa58abeec4c99e9b2cd25e550306d 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 6.12-y.cip 2/5] dt-bindings: net: renesas-gbeth: Add support for RZ/V2N (R9A09G056) SoC

[Ovidiu Panait]

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

commit 6b466efc6365e904b4b7eb65218a5b2969f978e2 upstream.

Document support for the GBETH IP found on the Renesas RZ/V2N (R9A09G056)
SoC. The GBETH controller on the RZ/V2N SoC is functionally identical to
the one found on the RZ/V2H(P) (R9A09G057) SoC, so `renesas,rzv2h-gbeth`
will be used as a fallback compatible.

[PATCH 6.12-y.cip 5/5] arm64: dts: renesas: r9a09g056n48-rzv2n-evk: Fix pinctrl node name for GBETH1

[Ovidiu Panait]

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

commit ed62c3807d3310f555ff02c1cd9b071d69faa38e 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".

6.1 version looked okay, and this looks okay, too. I'll run the tests
and likely apply it soon.
