From 830e0b0e15ee3d676539346b019f97f9bfae16b5 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 3 Mar 2026 14:52:23 -0600 Subject: [PATCH] arm64: dts: ti: k3-j7200: Make MAIN domain system control bus a simple-bus This node describes a memory address range containing several sub-regions with control registers for various IP in the MAIN domain of this SoC. It was described as a "ti,j721e-system-controller" but this is a J7200 SoC with is not compatible with the system controller region found in J721e. No project consuming this DT has been found that makes use of the syscon compatible for this region, to prevent any from using this node like a generic syscon region in the future, make this a normal simple-bus as it should have been from the start.
