From 30eb852aabff590cd3b1d5cb089b2e4341d05679 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Mon, 5 May 2025 09:45:47 -0500 Subject: [PATCH] dt-bindings: interrupt-controller: Convert amazon,al-fic to DT schema Convert the Amazon FIC interrupt controller binding to schema format. It's a straight-forward conversion of the typical interrupt controller.
