"kendryte" is the marketing name for the K210 RISC-V SoC produced by Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210" vendor,SoC compatibility string format in the device tree files and use the SoC name for file names. With these changes, the device tree files are more in sync with the Linux kernel DTS and drivers, making uboot device tree usable by the kernel.
