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.
power1_input System power consumption (microWatt)

Supported chips:

Prefix: 'powr1220'
Addresses scanned: none
Datasheet: Publicly available at the Lattice website
http://www.latticesemi.com/
Author: Scott Kanowitz <scott.kanowitz@gmail.com>
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
in2 VMON4
in4 VMON5
in5 VMON6
in6 VMON7
in7 VMON8
in8 VMON9
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.
