I was confused by the word base because in your example it is the context variable. Now i've successful tested my first version of the OCOTP driver based on NVMEM framework [1]. Currently only the raw sysfs access is working. So i have another question: How do i get the cell info from the devicetree for the nvmem_config? I expected a function like of_nvmem_cell_info_get() .
