[PATCH v2 5/8] arm64: dts: renesas: r9a09g077: add GPIO IRQ support

From: Cosmin Tanislav

Date: Fri Dec 05 2025 - 10:03:54 EST


The Renesas RZ/T2H (R9A09G077) SoC includes pins which can be routed via
the ICU to generate interrupts.

Add support for using the pin controller as an interrupt chip.
