Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon updates from Guenter Roeck: "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.

+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

+tempX_max Threshold ambient temperature for alert generation.
+inX_input Measured power supply voltage

+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:
+
+driver name pin name
+in0 VMON1
+in1 VMON2
+in2 VMON3

+in9 VMON10
+in10 VMON11
+in11 VMON12
+in12 VCCA
+in13 VCCINP
+
+The ADC readings are updated on request with a minimum period of 1s.

+Kernel driver pwm-fan
+=====================
+
+This driver enables the use of a PWM module to drive a fan. It uses the
+generic PWM interface thus it is hardware independent. It can be used on
+many SoCs, as long as the SoC supplies a PWM line driver that exposes
+the generic PWM API.
+
+Author: Kamil Debski <k.debski@samsung.com>
+
+Description
+-----------
+
+The driver implements a simple interface for driving a fan connected to
+a PWM output. It uses the generic PWM interface, thus it can be used with
+a range of SoCs. The driver exposes the fan to the user space through
+the hwmon's sysfs interface.

+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
+
+
+Sysfs entries
+-------------
+
+The following attributes are supported.
+
+in[1-2]_label "vout[1-2]"
+in[1-2]_input Measured voltage. From READ_VOUT register.
+in[1-2]_alarm voltage alarm.
+
+curr[1-2]_input Measured current. From READ_IOUT register.
+curr[1-2]_label "iout[1-2]"
+curr1_max Maximum current. From IOUT_OC_WARN_LIMIT register.
+curr1_crit Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
+curr1_max_alarm Current high alarm. From IOUT_OC_WARN_LIMIT status.
+curr1_crit_alarm Current critical high alarm. From IOUT_OC_FAULT status.
+curr2_alarm Current high alarm. From IOUT_OC_WARNING status.
+
+temp1_input Measured temperature. From READ_TEMPERATURE_2 register on page 0.
+temp1_max Maximum temperature. From OT_WARN_LIMIT register.
+temp1_crit Critical high temperature. From OT_FAULT_LIMIT register.
+temp1_max_alarm Chip temperature high alarm. Set by comparing
