Subject: [PATCH v2 0/2] Add ICU support for Renesas RZ/V2N SoC

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

Hi All,

This patch series aims to add support for the Interrupt Control Unit (ICU)
found in the Renesas RZ/V2N System on Chip (SoC). The RZ/V2N ICU shares
similarities with the RZ/V2H(P) family but has a different register layout,
notably with a reduced set of ECCRAM related registers.
The first patch documents the RZ/V2N ICU in the device tree bindings,
while the second patch introduces support in the irqchip driver by adding
a new compatible string.

v1->v2:
- Dropped using RZ/V2H compatible as a fallback.
- Patch 2/2 is new

Cheers,
Prabhakar
