-The MAXIM max6875 is a EEPROM-programmable power-supply sequencer/supervisor.
+The Maxim MAX6875 is an EEPROM-programmable power-supply sequencer/supervisor.
 It provides timed outputs that can be used as a watchdog, if properly wired.
 It also provides 512 bytes of user EEPROM.
 
-At reset, the max6875 reads the configuration eeprom into its configuration
+At reset, the MAX6875 reads the configuration EEPROM into its configuration
 registers.  The chip then begins to operate according to the values in the
 registers.
 
+The Maxim MAX6874 is a similar, mostly compatible device, with more intputs
+and outputs:
+
+             vin     gpi    vout
+MAX6874        6       4       8
+MAX6875        4       3       5
+
+MAX6874 chips can have four different addresses (as opposed to only two for
+the MAX6875). The additional addresses (0x54 and 0x56) are not probed by
+this driver by default, but the probe module parameter can be used if
+needed.

 See the datasheet for details on how to program the EEPROM.
