+ Work in progress statement:
+
+ Device tree files and bindings applying to Amlogic SoCs and boards are
+ considered "unstable". Any Amlogic device tree binding may change at
+ any time. Be sure to use a device tree binary and a kernel image
+ generated from the same source tree.
+
+ Please refer to Documentation/devicetree/bindings/ABI.rst for a definition of a
+ stable binding/ABI.
