 "Notable changes:

   - Heiko Schocher provided a driver for TI TMP103.
   - Kamil Debski provided a driver for pwm-controlled fans.
   - Neelesh Gupta provided a driver for power, fan rpm, voltage and
     temperature reporting on powerpc/powernv systems.
   - Scott Kanowitz provided a driver supporting Lattice's POWR1220
     power manager IC.
   - Richard Zhu provided a pmbus front-end driver for TPS40422.
   - Frans Klaver added support for TMP112 to the lm75 driver.
   - Johannes Pointner added support for EPCOS B57330V2103 to the
     ntc_thermistor driver.
   - Guenter Roeck added support for TMP441 and TMP442 to the tmp421
     driver.
   - Axel Lin converted several drivers to the new hwmon API (36 of
     them, if I counted correctly), and cleaned up many of the drivers
     along the way.

  There are also a number of patches fixing bugs discovered while
  testing Axel's changes"

+Kernel Driver IBMPOWERNV
+========================
+
+Supported systems:
+  * Any recent IBM P servers based on POWERNV platform
+
+Author: Neelesh Gupta
+
+Description
+-----------
+
+This driver implements reading the platform sensors data like temperature/fan/
+voltage/power for 'POWERNV' platform.
+
+The driver uses the platform device infrastructure. It probes the device tree
+for sensor devices during the __init phase and registers them with the 'hwmon'.
+'hwmon' populates the 'sysfs' tree having attribute files, each for a given
+sensor type and its attribute data.
+
+All the nodes in the DT appear under "/ibm,opal/sensors" and each valid node in
+the DT maps to an attribute file in 'sysfs'. The node exports unique 'sensor-id'
+which the driver uses to make an OPAL call to the firmware.
+
+Usage notes
+-----------
+The driver is built statically with the kernel by enabling the config
+CONFIG_SENSORS_IBMPOWERNV. It can also be built as module 'ibmpowernv'.
+
+Sysfs attributes
+----------------
+
+fanX_input		Measured RPM value.
+fanX_min		Threshold RPM for alert generation.
+fanX_fault		0: No fail condition
+			1: Failing fan
+tempX_input		Measured ambient temperature.
+tempX_max		Threshold ambient temperature for alert generation.
+inX_input		Measured power supply voltage
+inX_fault		0: No fail condition.
+			1: Failing power supply.

+Description
+-----------
+
+This driver supports the Lattice POWR1220AT8 chip. The POWR1220
+includes voltage monitoring for 14 inputs as well as trim settings
+for output voltages and GPIOs. This driver implements the voltage
+monitoring portion of the chip.
+
+Voltages are sampled by a 12-bit ADC with a step size of 2 mV.
+An in-line attenuator allows measurements from 0 to 6 V. The
+attenuator is enabled or disabled depending on the setting of the
+input's max value. The driver will enable the attenuator for any
+value over the low measurement range maximum of 2 V.
+
+The input naming convention is as follows:

+Kernel driver pwm-fan
+=====================
+
+This driver enables the use of a PWM module to drive a fan. It uses the

+the generic PWM API.

+The driver implements a simple interface for driving a fan connected to
