Subject: [PATCH v6 3/4] arm64: dts: ti: k3-am62l: add initial
infrastructure
From: Vignesh Raghavendra <vigneshr@...com>
Add the initial infrastructure needed for the AM62L. ALl of which can be
found in the Technical Reference Manual (TRM) located here:

Changes in v4:
- Corrected Copyright year
- Used 'ranges' property in the fss{} node
Changes in v3:
- Added more nodes now that the SCMI interface is ready
Changes in v1:
- switched to non-direct links to TRM updates are automatic
- fixed white space indent issues with a few nodes
- separated out device tree bindings
