From 62c427ca0745d54c7b715923633ced3e34453722 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 14 Jun 2022 09:25:03 -0600 Subject: [PATCH] dt-bindings: dma: apple,admac: Fix example interrupt parsing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 873971f8fb08 ("dt-bindings: dma: Add Apple ADMAC") has a warning in its example: Documentation/devicetree/bindings/dma/apple,admac.example.dtb: dma-controller@238200000: interrupts-extended: [[0], [4294967295, 0, 626, 4, 0, 0]] is too short From schema: /builds/robherring/linux-dt/Documentation/devicetree/bindings/dma/apple,admac.yaml The problem is the number of interrupt cells can't be guessed when there are empty '0' entries. So the example must have a valid interrupt controller defining the number of interrupt cells.
