From c71869c61d7cf2070421cdcc4dd64c4c860df49d Mon Sep 17 00:00:00 2001 From: Lad Prabhakar Date: Thu, 27 Nov 2025 16:24:46 +0000 Subject: [PATCH] dt-bindings: interrupt-controller: renesas,rzv2h-icu: Document RZ/V2N SoC Document the Interrupt Control Unit (ICU) used on the Renesas RZ/V2N SoC. Although the ICU closely matches the design found on the RZ/V2H(P) family, it differs in its register layout, particularly in the reduced set of ECCRAM related registers. These variations require a distinct compatible string so that software can correctly match and handle the RZ/V2N implementation.
