Kernel driver ina209

Description
-----------
The TI / Burr-Brown INA209 monitors voltage, current, and power on the high side
of a D.C. power supply. It can perform measurements and calculations in the
background to supply readings at any time. It includes a programmable
calibration multiplier to scale the displayed current and power values.
Sysfs entries
-------------
The INA209 chip is highly configurable both via hardwiring and via
the I2C bus. See the datasheet for details.
This tries to expose most monitoring features of the hardware via
sysfs. It does not support every feature of this chip.

update_interval data conversion time; affects number of samples used
to average results for shunt and bus voltages.
General Remarks
---------------
The power and current registers in this chip require that the calibration
register is programmed correctly before they are used. Normally this is expected
to be done in the BIOS. In the absence of BIOS programming, the shunt resistor
voltage can be provided using platform data. The driver uses platform data from
the ina2xx driver for this purpose. If calibration register data is not provided
via platform data, the driver checks if the calibration register has been
programmed (ie has a value not equal to zero). If so, this value is retained.
Otherwise, a default value reflecting a shunt resistor value of 10 mOhm is
programmed into the calibration register.
Output Pins
-----------
Output pin programming is a board feature which depends on the BIOS. It is
outside the scope of a hardware monitoring driver to enable or disable output
pins.

Kernel driver lm73
==================
Supported chips:
* Texas Instruments LM73
Prefix: 'lm73'
Addresses scanned: I2C 0x48, 0x49, 0x4a, 0x4c, 0x4d, and 0x4e
Datasheet: Publicly available at the Texas Instruments website
http://www.ti.com/product/lm73
Author: Guillaume Ligneul <guillaume.ligneul@gmail.com>
Documentation: Chris Verges <kg4ysn@gmail.com>
Description
-----------
The LM73 is a digital temperature sensor. All temperature values are
given in degrees Celsius.
Measurement Resolution Support
------------------------------
The LM73 supports four resolutions, defined in terms of degrees C per
LSB: 0.25, 0.125, 0.0625, and 0.3125. Changing the resolution mode
affects the conversion time of the LM73's analog-to-digital converter.
From userspace, the desired resolution can be specified as a function of
conversion time via the 'update_interval' sysfs attribute for the
device. This attribute will normalize ranges of input values to the
maximum times defined for the resolution in the datasheet.
Resolution Conv. Time Input Range
(C/LSB) (msec) (msec)
--------------------------------------
0.25 14 0..14
0.125 28 15..28
0.0625 56 29..56
0.03125 112 57..infinity
--------------------------------------
The following examples show how the 'update_interval' attribute can be
used to change the conversion time:
$ echo 0 > update_interval
$ cat update_interval
14
$ cat temp1_input
24250
$ echo 22 > update_interval
$ cat update_interval
28
$ cat temp1_input
24125
$ echo 56 > update_interval
$ cat update_interval
56
$ cat temp1_input
24062
$ echo 85 > update_interval
$ cat update_interval
112
$ cat temp1_input
24031
As shown here, the lm73 driver automatically adjusts any user input for
'update_interval' via a step function. Reading back the
'update_interval' value after a write operation will confirm the
conversion time actively in use.
Mathematically, the resolution can be derived from the conversion time
via the following function:
g(x) = 0.250 * [log(x/14) / log(2)]
where 'x' is the output from 'update_interval' and 'g(x)' is the
resolution in degrees C per LSB.
Alarm Support
-------------
The LM73 features a simple over-temperature alarm mechanism. This
feature is exposed via the sysfs attributes.
The attributes 'temp1_max_alarm' and 'temp1_min_alarm' are flags
provided by the LM73 that indicate whether the measured temperature has
passed the 'temp1_max' and 'temp1_min' thresholds, respectively. These
values _must_ be read to clear the registers on the LM73.

Description
-----------
This driver implements support for several MAX6697 compatible temperature sensor
chips. The chips support one local temperature sensor plus four, six, or seven
remote temperature sensors. Remote temperature sensors are diode-connected
thermal transitors, except for MAX6698 which supports three diode-connected
thermal transistors plus three thermistors in addition to the local temperature
sensor.
The driver provides the following sysfs attributes. temp1 is the local (chip)
temperature, temp[2..n] are remote temperatures. The actually supported
per-channel attributes are chip type and channel dependent.
tempX_input RO temperature
tempX_max RW temperature maximum threshold
tempX_max_alarm RO temperature maximum threshold alarm
tempX_crit RW temperature critical threshold
tempX_crit_alarm RO temperature critical threshold alarm
tempX_fault RO temperature diode fault (remote sensors only)

If you say yes here you get hardware monitoring support for Maxim
MAX34440, MAX34441, and MAX34446.
MAX34440, MAX34441, MAX34446, MAX34460, and MAX34461.
This driver can also be built as a module. If so, the module will
be called max34440.
