Hi, Mason, YC Lin, We'll have to figure out how we can best use the "Command Sequences to Change to Octal DDR" table. Would be great if you continue to work on this. One has to rebase this series on top of v5.10-rc1 with Pratyush's series [1] applied in advance. Please let me know about your plans with this series. Cheers, ta [1] https://patchwork.ozlabs.org/project/linux-mtd/cover/20201005153138.6437-1-p.yadav@xxxxxx/
