ARM SoC maintainers, At least on a quick look (I could be wrong), I
think we don't have any explicit processor bindings documentation.
However, most of SoC folks seem to key off matches else where I
guess..
Not sure, while at this, you if you are planning on fixing up
Documentation/devicetree/bindings/arm/arm-boards:
compatible = "arm,cortex-a53","arm,armv8";
Documentation/devicetree/bindings/arm/cpu-capacity.txt:
compatible = "arm,cortex-a53","arm,armv8";
Anyways, for TI SoC:
