From 815d7b2c13590a77b295d0330c31429d367f2ece Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Mon, 5 May 2025 09:46:04 -0500 Subject: [PATCH] dt-bindings: interrupt-controller: Convert aspeed,ast2400-i2c-ic to DT schema Convert the Aspeed I2C interrupt controller binding to schema format. Drop the "#address-cells" and "#size-cells" as they are unused and incorrect anyways.
