Subject: riscv: dts: canaan: Add k210 topology information
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e751030eb8448f026a71f0166d2c988fe1e49dbb;p=linux.git

riscv: dts: canaan: Add k210 topology information

[ Upstream commit d9d193dea8666bbf69fc21c5bdcdabaa34a466e3 ]

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