Subject: [PATCH 0/6] irqchip/renesas-rzv2h: Add support to handle ICU error IRQ and add SWPE trigger

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

Hi All,

This patch series aims to enhance the Renesas RZ/V2H ICU irqchip driver by
adding support to handle ICU error IRQs and introducing a
software-generated interrupt (SWPE) trigger. The series includes the
following changes:
- Use local pointers for device tree nodes and devices
- Switch to using dev_err_probe()
- Add software-triggered interrupt support
- Add handling for ICU error IRQs and SWPE trigger
- Document the new debugfs triggers

Cheers,
Prabhakar
