From 8b12070746854a70bd43d5763562561efc1840de Mon Sep 17 00:00:00 2001 From: Cosmin Tanislav Date: Fri, 5 Dec 2025 17:02:29 +0200 Subject: [PATCH] dt-bindings: pinctrl: renesas,r9a09g077-pinctrl: Document GPIO IRQ The Renesas RZ/T2H (R9A09G077) and Renesas RZ/N2H (R9A09G087) SoCs have IRQ-capable pins handled by the ICU, which forwards them to the GIC. The ICU supports 16 IRQ lines, the pins map to these lines arbitrarily, and the mapping is not configurable. Document the required properties to handle GPIO IRQ.
