* Returns 0 on success or an appropriate negative error number on failure.
* All child-devices of the MFD will automatically be removed when it gets
* unbinded.
+ *
+ * @dev: Pointer to parent device.
+ * @id: Can be PLATFORM_DEVID_AUTO to let the Platform API take care
+ * of device numbering, or will be added to a device's cell_id.
+ * @cells: Array of (struct mfd_cell)s describing child devices.
+ * @n_devs: Number of child devices to register.
+ * @mem_base: Parent register range resource for child devices.
+ * @irq_base: Base of the range of virtual interrupt numbers allocated for
+ * this MFD device. Unused if @domain is specified.
+ * @domain: Interrupt domain to create mappings for hardware interrupts.
