- * As seen through Linux I2C, differences between the most common types of I2C
- * memory include:
- * - How much memory is available (usually specified in bit)?
- * - What write page size does it support?
- * - Special flags (16 bit addresses, read_only, world readable...)?
+/**
+ * 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 memory_accessor, 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 memory_accessor *mem_acc, void *context)
+ * {
+ *      u8 *mac_addr = ethernet_pdata->mac_addr;
+ *      off_t offset = context;
+ *
+ *      // Read MAC addr from EEPROM
+ *      if (mem_acc->read(mem_acc, mac_addr, offset, ETH_ALEN) == 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.
