Subject: [PATCH v1 0/2] dt-bindings: Add a cpu-capacity property for RISC-V

From: Conor Dooley <conor.dooley@...rochip.com>

Hey,

Ever since RISC-V starting using generic arch topology code, the code
paths for cpu-capacity have been there but there's no binding defined to
actually convey the information. Defining the same property as used on
arm seems to be the only logical thing to do, so do it.

It's worth noting that right now, actually putting this property in a DT
will cause allocation failures on RISC-V - but there's already a patch
for that thanks to Ley Foon Tan:

Thanks,
Conor.
