Hi, I have the same problem. https://lore.kernel.org/all/CALHCpMgEZjnR39upkR6iozSk-b5A_GHRo9rcDSPXzzQi6x_qCw@xxxxxxxxxxxxxx/ I think the root of the problem was the choice of 'compatible' device tree property to marking mtd partition node as a nvmem provider. This property used only inside 'mtd_nvmem_add' function to setup 'no_of_node' flag. > config.no_of_node = !of_device_is_compatible(node, "nvmem-cells"); This is how this flag processed by 'nvmem_register' function. > if (config->of_node) > nvmem->dev.of_node = config->of_node; > else if (!config->no_of_node) > nvmem->dev.of_node = config->dev->of_node; Thats all, there is no such driver which compatible with 'nvmem-cells'. So, maybe we should change the 'compatible' property to something else?
