@@ -285,6 +453,12 @@ The LM90 is a digital temperature sensor. It senses its own temperature as
 well as the temperature of up to one external diode. It is compatible
 with many other devices, many of which are supported by this driver.
 
+The family of chips supported by this driver is derived from MAX1617.
+This chip as well as various compatible chips support a local and a remote
+temperature sensor with 8 bit accuracy. Later chips provide improved accuracy
+and other additional features such as hysteresis and temperature offset

 Note that there is no easy way to differentiate between the MAX6657,
 MAX6658 and MAX6659 variants. The extra features of the MAX6659 are only
 supported by this driver if the chip is located at address 0x4d or 0x4e,

+Description
+-----------
+
+LT7182S is a Dual Channel 6A, 20V PolyPhase Step-Down Silent Switcher with
+Digital Power System Management support.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+Example: the following commands will load the driver for a LT7182S
+at address 0x4f on I2C bus #4::
+
+    # modprobe lt7182s
+    # echo lt7182s 0x4f > /sys/bus/i2c/devices/i2c-4/new_device
+
+It can also be instantiated by declaring an entry in device tree.

+PEC Support
+===========
+
+Many PMBus devices support SMBus PEC (Packet Error Checking). If supported

+If PEC is supported, the PMBus core driver adds an attribute named 'pec' to
