-
-    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
