- * struct at24_platform_data - data to set up at24 (generic eeprom) driver
- * @byte_len: size of eeprom in byte
- * @page_size: number of byte which can be written in one go
- * @flags: tunable options, check AT24_FLAG_* defines
- * @setup: an optional callback invoked after eeprom is probed; enables kernel
-	code to access eeprom via nvmem, see example
- * @context: optional parameter passed to setup()
- *
- * If you set up a custom eeprom type, please double-check the parameters.
- * Especially page_size needs extra care, as you risk data loss if your value
- * is bigger than what the chip actually supports!
- *
- * An example in pseudo code for a setup() callback:
- *
- * void get_mac_addr(struct nvmem_device *nvmem, void *context)
- * {
- *	u8 *mac_addr = ethernet_pdata->mac_addr;
- *	off_t offset = context;
- *
- *	// Read MAC addr from EEPROM
- *	if (nvmem_device_read(nvmem, offset, ETH_ALEN, mac_addr) == ETH_ALEN)
- *		pr_info("Read MAC addr from EEPROM: %pM\n", mac_addr);
- * }
- *
- * This function pointer and context can now be set up in at24_platform_data.
