From b3f629482cade3a6ada44d2e83dd65f0f1ed1293 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 26 Mar 2024 15:59:20 -0500 Subject: [PATCH] arm64: dts: ti: k3-j784s4: Use exact ranges for FSS node The FSS bus contains several register ranges. Using an empty ranges property works but causes a DT warning when we give this node an address. Fix this by explicitly defining the memory ranges in use.
