-
- Copyright (C) 2005 Ben Gardner <bgardner@wabtec.com>
-
- Based on eeprom.c
-
- The MAX6875 has a bank of registers and two banks of EEPROM.
- Address ranges are defined as follows:
- * 0x0000 - 0x0046 = configuration registers
- * 0x8000 - 0x8046 = configuration EEPROM
- * 0x8100 - 0x82FF = user EEPROM
-
- This driver makes the user EEPROM available for read.
-
- The registers & config EEPROM should be accessed via i2c-dev.
-
- The MAX6875 ignores the lowest address bit, so each chip responds to
- two addresses - 0x50/0x51 and 0x52/0x53.
-
- Note that the MAX6875 uses i2c_smbus_write_byte_data() to set the read
- address, so this driver is destructive if loaded for the wrong EEPROM chip.
