[v5] irqchip/renesas-rzv2h: Add support to handle ICU error IRQ and add SWPE trigger

[PATCH v5 1/7] irqchip/renesas-rzv2h: Use local node pointer

Posted by Prabhakar 4 weeks ago

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

Avoid dereferencing pdev->dev.of_node again in rzv2h_icu_probe_common().
Reuse the already available local node pointer when mapping the ICU
register space.
