[PATCH 5/5] riscv: dts: canaan: Add k210 topology information

From: Conor Dooley
Date: Tue Jul 05 2022 - 15:05:18 EST


From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

The k210 has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.
