From 75a21ed9d0a959c979c5300950bf60dfca20b90e Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Tue, 7 Mar 2023 19:39:59 +0100 Subject: [PATCH] ARM: dts: imx28-apf28: Convert to use label references These Armadeus board files still use node name and unit address to reference parts from the imx28.dtsi . This causes a lot of redundancy. So use label references in order to make it easier to maintain.
