Subject: [PATCH 2/4] arm64: dts: ti: k3-j7200: Use exact ranges for FSS node
Date: Tue, 26 Mar 2024 15:59:18 -0500

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.
