+Kernel driver max1668
+=====================
+
+Supported chips:
+  * Maxim MAX1668, MAX1805 and MAX1989
+    Prefix: 'max1668'
+    Addresses scanned: I2C 0x18, 0x19, 0x1a, 0x29, 0x2a, 0x2b, 0x4c, 0x4d, 0x4e
+    Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX1668-MAX1989.pdf
+
+Author:
+    David George <david.george@ska.ac.za>
+
+Description
+-----------
+
+This driver implements support for the Maxim MAX1668, MAX1805 and MAX1989
+chips.
+
+The three devices are very similar, but the MAX1805 has a reduced feature
+set; only two remote temperature inputs vs the four avaible on the other
+two ICs.
+
+The driver is able to distinguish between the devices and creates sysfs
+entries as follows:
+
+MAX1805, MAX1668 and MAX1989:
+
+temp1_input     ro local (ambient) temperature
+temp1_max       rw local temperature maximum threshold for alarm
+temp1_max_alarm ro local temperature maximum threshold alarm
+temp1_min       rw local temperature minimum threshold for alarm
+temp1_min_alarm ro local temperature minimum threshold alarm
+temp2_input     ro remote temperature 1
+temp2_max       rw remote temperature 1 maximum threshold for alarm
+temp2_max_alarm ro remote temperature 1 maximum threshold alarm
+temp2_min       rw remote temperature 1 minimum threshold for alarm
+temp2_min_alarm ro remote temperature 1 minimum threshold alarm
+temp3_input     ro remote temperature 2
+temp3_max       rw remote temperature 2 maximum threshold for alarm
+temp3_max_alarm ro remote temperature 2 maximum threshold alarm
+temp3_min       rw remote temperature 2 minimum threshold for alarm
+temp3_min_alarm ro remote temperature 2 minimum threshold alarm
+
+MAX1668 and MAX1989 only:
+temp4_input     ro remote temperature 3
+temp4_max       rw remote temperature 3 maximum threshold for alarm
+temp4_max_alarm ro remote temperature 3 maximum threshold alarm
+temp4_min       rw remote temperature 3 minimum threshold for alarm
+temp4_min_alarm ro remote temperature 3 minimum threshold alarm
+temp5_input     ro remote temperature 4
+temp5_max       rw remote temperature 4 maximum threshold for alarm
+temp5_max_alarm ro remote temperature 4 maximum threshold alarm
+temp5_min       rw remote temperature 4 minimum threshold for alarm
+temp5_min_alarm ro remote temperature 4 minimum threshold alarm
+
+Module Parameters
+-----------------
+
+* read_only: int
+  Set to non-zero if you wish to prevent write access to alarm thresholds.
