Hi, I am working on writing dts for a new SOC - SG2042, you can see the changes on https://github.com/unicornx/linux-riscv/commit/ee862fc4ebeade32bff00ad014d6b0513c0942a7. This hardware uses a NUMA architecture, so a "distance-map" node is added and several "numa-node-id" are added for cpu/memory. The problem is I find there is no YAML binding for numa, I only find "Documentation/devicetree/bindings/numa.txt". To pass dtb check I want to convert the txt to yaml file. My question is: how to handle the "numa-node-id" which is listed in the numa.txt file. To my understanding, due to cpu/memory node need to contain this property. I should find some binding files for cpu/memory and add "numa-node-id" for cpu/memory. For "cpu", I find a "Documentation/devicetree/bindings/riscv/cpus.yaml", where I think I can add a property of "numa-node-id" to. Note the SG2042 is a RISC-V chip. But for "memory", where should I add "numa-node-id" definition to? Regards, Chen Wang
