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

Conor Dooley mail at conchuod.ie
Tue Jul 5 12:04:36 PDT 2022


From: Conor Dooley <conor.dooley at microchip.com>

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