* struct nvmem_config - NVMEM device configuration
*
* @dev: Parent device.
* @name: Optional name.
* @id: Optional device ID used in full name. Ignored if name is NULL.
* @owner: Pointer to exporter module. Used for refcounting.
* @cells: Optional array of pre-defined NVMEM cells.
* @ncells: Number of elements in cells.
* @read_only: Device is read-only.
* @root_only: Device is accessibly to root only.
* @reg_read: Callback to read data.
* @reg_write: Callback to write data.
* @size: Device size.
* @word_size: Minimum read/write access granularity.
* @stride: Minimum read/write access stride.
* @priv: User context passed to read/write callbacks.
*
* Note: A default "nvmem<id>" name will be assigned to the device if
* no name is specified in its configuration. In such case "<id>" is
* generated with ida_simple_get() and provided id field is ignored.
