[PATCH 3/4] arm64: dts: ti: k3-j721e: Use exact ranges for FSS node

From: Andrew Davis
Date: Tue Mar 26 2024 - 17:00:13 EST


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.
