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 interrupts using SWPE and SWINT. The series includes the
following changes:
1. Use local node pointer
2. Use local device pointer in ICU probe
3. Switch to using dev_err_probe()
4. Make IRQ type handling range-aware
5. Add CA55 software interrupt support
6. Handle ICU error IRQ and add SWPE trigger

v2->v3:
- Updated the check in rzv2h_icu_alloc() to ensure hwirq is within the
  TINT range when extracting TINT information in patch 4/6.
- Replaced pr_debug with pr_info in the SWINT handler in patch 5/6
  and 6/6 to ensure  visibility of the message.

v1->v2:
- No changes for patches 1-3.
- Patch 4 is a new patch.
- Patch 5
  - Made CA55 SW interrupt as part of ICU IRQ domain.
  - Implemented rzv2h_icu_irq_set_irqchip_state() to trigger SWINT.
  - Updated commit message accordingly.
- Patch 6
  - Made Error interrupt as part of ICU IRQ domain.
  - Updated rzv2h_icu_irq_set_irqchip_state() to trigger pseudo interrupt.
  - Updated commit message accordingly.

Cheers,
Prabhakar
