When: June 2011
Why: The adm9240, w83792d and w83793 hardware monitoring drivers have
legacy interfaces for chassis intrusion detection. A standard
interface has been added to each driver, so the legacy interface

Kernel driver adt7410
=====================
Supported chips:
* Analog Devices ADT7410
Prefix: 'adt7410'
Addresses scanned: I2C 0x48 - 0x4B
Datasheet: Publicly available at the Analog Devices website
http://www.analog.com/static/imported-files/data_sheets/ADT7410.pdf
Author: Hartmut Knaack <knaack.h@gmx.de>
Description
-----------
The ADT7410 is a temperature sensor with rated temperature range of -55°C to
+150°C. It has a high accuracy of +/-0.5°C and can be operated at a resolution
of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an INT pin to
indicate that a minimum or maximum temperature set point has been exceeded, as
well as a critical temperature (CT) pin to indicate that the critical
temperature set point has been exceeded. Both pins can be set up with a common
hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events. Both
pins can individually set to be active-low or active-high, while the whole
device can either run in comparator mode or interrupt mode. The ADT7410
supports continous temperature sampling, as well as sampling one temperature
value per second or even justget one sample on demand for power saving.
Besides, it can completely power down its ADC, if power management is
required.
Configuration Notes
-------------------
Since the device uses one hysteresis value, which is an offset to minimum,
maximum and critical temperature, it can only be set for temp#_max_hyst.
However, temp#_min_hyst and temp#_crit_hyst show their corresponding
hysteresis.
The device is set to 16 bit resolution and comparator mode.
sysfs-Interface
---------------
temp#_input - temperature input
temp#_min - temperature minimum setpoint
temp#_max - temperature maximum setpoint
temp#_crit - critical temperature setpoint
temp#_min_hyst - hysteresis for temperature minimum (read-only)
temp#_max_hyst - hysteresis for temperature maximum (read/write)
temp#_crit_hyst - hysteresis for critical temperature (read-only)
temp#_min_alarm - temperature minimum alarm flag
temp#_max_alarm - temperature maximum alarm flag
temp#_crit_alarm - critical temperature alarm flag

Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX197.pdf
* Maxim MAX199
Prefix: 'max199'
Datasheet: http://datasheets.maxim-ic.com/en/ds/MAX199.pdf
Description
-----------
The A/D converters MAX197, and MAX199 are both 8-Channel, Multi-Range, 5V,
12-Bit DAS with 8+4 Bus Interface and Fault Protection.
The available ranges for the MAX197 are {0,-5V} to 5V, and {0,-10V} to 10V,
while they are {0,-2V} to 2V, and {0,-4V} to 4V on the MAX199.
Platform data
-------------
The MAX197 platform data (defined in linux/platform_data/max197.h) should be
filled with a pointer to a conversion function, defined like:
int convert(u8 ctrl);
ctrl is the control byte to write to start a new conversion.
On success, the function must return the 12-bit raw value read from the chip,
or a negative error code otherwise.
Control byte format:
Bit Name Description
7,6 PD1,PD0 Clock and Power-Down modes
5 ACQMOD Internal or External Controlled Acquisition
4 RNG Full-scale voltage magnitude at the input
3 BIP Unipolar or Bipolar conversion mode
2,1,0 A2,A1,A0 Channel
Sysfs interface
---------------
* in[0-7]_input: The conversion value for the corresponding channel.
RO
* in[0-7]_min: The lower limit (in mV) for the corresponding channel.
For the MAX197, it will be adjusted to -10000, -5000, or 0.
For the MAX199, it will be adjusted to -4000, -2000, or 0.
RW
* in[0-7]_max: The higher limit (in mV) for the corresponding channel.
For the MAX197, it will be adjusted to 0, 5000, or 10000.
