|
(one device per address in this address range: 0x48..0x4f).
|
||||||
|
|
||||||
|
The DS1625 is pin compatible and functionally equivalent with the DS1621,
|
||||||
|
but the DS1621 is meant to replace it. The DS1631, DS1721, and DS1731 are
|
||||||
|
also pin compatible with the DS1621 and provide multi-resolution support.
|
||||||
|
|
||||||
|
Additionally, the DS1721 data sheet says the temperature flags (THF and TLF)
|
||||||
|
are used internally, however, these flags do get set and cleared as the actual
|
||||||
|
temperature crosses the min or max settings (which by default are set to 75
|
||||||
|
and 80 degrees respectively).
|
||||||
|
|
||||||
|
Temperature Conversion:
|
||||||
|
-----------------------
|
||||||
|
DS1621 - 750ms (older devices may take up to 1000ms)
|
||||||
|
DS1625 - 500ms
|
||||||
|
DS1631 - 93ms..750ms for 9..12 bits resolution, respectively.
|
||||||
|
DS1721 - 93ms..750ms for 9..12 bits resolution, respectively.
|
||||||
|
DS1731 - 93ms..750ms for 9..12 bits resolution, respectively.
|
||||||
|
|
||||||
|
Note:
|
||||||
|
On the DS1621, internal access to non-volatile registers may last for 10ms
|
||||||
|
or less (unverified on the other devices).
|
||||||
|
|
||||||
|
Temperature Accuracy:
|
||||||
|
---------------------
|
||||||
|
DS1621: +/- 0.5 degree Celsius (from 0 to +70 degrees)
|
||||||
|
DS1625: +/- 0.5 degree Celsius (from 0 to +70 degrees)
|
||||||
|
DS1631: +/- 0.5 degree Celsius (from 0 to +70 degrees)
|
||||||
|
DS1721: +/- 1.0 degree Celsius (from -10 to +85 degrees)
|
||||||
|
DS1731: +/- 1.0 degree Celsius (from -10 to +85 degrees)
|
||||||
|
|
||||||
|
Note:
|
||||||
|
Please refer to the device datasheets for accuracy at other temperatures.
|
||||||
|
|
||||||
|
Temperature Resolution:
|
||||||
|
-----------------------
|
||||||
|
As mentioned above, the DS1631, DS1721, and DS1731 provide multi-resolution
|
||||||
|
support, which is achieved via the R0 and R1 config register bits, where:
|
||||||
|
|
||||||
|
R0..R1
|
||||||
|
------
|
||||||
|
0 0 => 9 bits, 0.5 degrees Celcius
|
||||||
|
1 0 => 10 bits, 0.25 degrees Celcius
|
||||||
|
0 1 => 11 bits, 0.125 degrees Celcius
|
||||||
|
1 1 => 12 bits, 0.0625 degrees Celcius
|
||||||
|
|
||||||
|
Note:
|
||||||
|
At initial device power-on, the default resolution is set to 12-bits.
|
||||||
|
|
||||||
|
The resolution mode for the DS1631, DS1721, or DS1731 can be changed from
|
||||||
|
userspace, via the device 'update_interval' sysfs attribute. This attribute
|
||||||
|
will normalize the range of input values to the device maximum resolution
|
||||||
|
values defined in the datasheet as follows:
|
||||||
|
|
||||||
|
Resolution Conversion Time Input Range
|
||||||
|

||||||

|
||||||
|
0.0625 750 376..infinity
|
||||||
|
------------------------------------------------
|
||||||
|
|
||||||
|
The following examples show how the 'update_interval' attribute can be
|
||||||
|
used to change the conversion time:
|
||||||
|
|
||||||
|
$ cat update_interval
|
||||||
|
750
|
||||||
|
$ cat temp1_input
|
||||||
|

|
||||||
|
$
|
||||||
|
$ echo 300 > update_interval
|
||||||
|
$ cat update_interval
|
||||||
|
375
|
||||||
|
$ cat temp1_input
|
||||||
|
22125
|
||||||
|
$
|
||||||
|
$ echo 150 > update_interval
|
||||||
|
$ cat update_interval
|
||||||
|
188
|
||||||
|
$ cat temp1_input
|
||||||
|
22250
|
||||||
|
$
|
||||||
|
$ echo 1 > update_interval
|
||||||
|
$ cat update_interval
|
||||||
|
94
|
||||||
|
$ cat temp1_input
|
||||||
|
22000
|
||||||
|
$
|
||||||
|
$ echo 1000 > update_interval
|
||||||
|
$ cat update_interval
|
||||||
|
750
|
||||||
|
$ cat temp1_input
|
||||||
|
22062
|
||||||
|
$
|
||||||
|
|
||||||
|
As shown, the ds1621 driver automatically adjusts the 'update_interval'
|
||||||
|
user input, via a step function. Reading back the 'update_interval' value
|
||||||
|
after a write operation provides the conversion time used by the device.
|
||||||
|
|
||||||
|
Mathematically, the resolution can be derived from the conversion time
|
||||||
|
via the following function:
|
||||||
|
|
||||||
|
g(x) = 0.5 * [minimum_conversion_time/x]
|
||||||
|
|
||||||
|
where:
|
||||||
|
-> 'x' = the output from 'update_interval'
|
||||||
|
-> 'g(x)' = the resolution in degrees C per LSB.
|
||||||
|
-> 93.75ms = minimum conversion time

Kernel driver g762
|
||||||
|
==================
|
||||||
|
|
||||||
|
The GMT G762 Fan Speed PWM Controller is connected directly to a fan
|
||||||
|
and performs closed-loop or open-loop control of the fan speed. Two
|
||||||
|
modes - PWM or DC - are supported by the device.
|
||||||
|
|
||||||
|
For additional information, a detailed datasheet is available at
|
||||||
|
http://natisbad.org/NAS/ref/GMT_EDS-762_763-080710-0.2.pdf. sysfs
|
||||||
|
bindings are described in Documentation/hwmon/sysfs-interface.
|
||||||
|
|
||||||
|
The following entries are available to the user in a subdirectory of
|
||||||
|
/sys/bus/i2c/drivers/g762/ to control the operation of the device.
|
||||||
|
This can be done manually using the following entries but is usually
|
||||||
|
done via a userland daemon like fancontrol.
|
||||||
|
|
||||||
|
Note that those entries do not provide ways to setup the specific
|
||||||
|
hardware characteristics of the system (reference clock, pulses per
|
||||||
|
fan revolution, ...); Those can be modified via devicetree bindings
|
||||||
|
documented in Documentation/devicetree/bindings/hwmon/g762.txt or
|
||||||
|
using a specific platform_data structure in board initialization
|
||||||
|
file (see include/linux/platform_data/g762.h).
|
||||||
|
|
||||||
|
fan1_target: set desired fan speed. This only makes sense in closed-loop
|
||||||
|
fan speed control (i.e. when pwm1_enable is set to 2).
|
||||||
|
|
||||||
|
fan1_input: provide current fan rotation value in RPM as reported by
|
||||||
|
the fan to the device.
|
||||||
|
|
||||||
|
fan1_div: fan clock divisor. Supported value are 1, 2, 4 and 8.
|
||||||
|
|
||||||
|
fan1_pulses: number of pulses per fan revolution. Supported values
|
||||||
|
are 2 and 4.
|
||||||
|
|
||||||
|
fan1_fault: reports fan failure, i.e. no transition on fan gear pin for
|
||||||
|
about 0.7s (if the fan is not voluntarily set off).
|
||||||
|
|
||||||
|
fan1_alarm: in closed-loop control mode, if fan RPM value is 25% out
|
||||||
|
of the programmed value for over 6 seconds 'fan1_alarm' is
|
||||||
|
set to 1.
|
||||||
|
|
||||||
|
pwm1_enable: set current fan speed control mode i.e. 1 for manual fan
|
||||||
|
speed control (open-loop) via pwm1 described below, 2 for
|
||||||
|
automatic fan speed control (closed-loop) via fan1_target
|
||||||
|
above.
|
||||||
|
|
||||||
|
pwm1_mode: set or get fan driving mode: 1 for PWM mode, 0 for DC mode.
|
||||||
|
|
||||||
|
pwm1: get or set PWM fan control value in open-loop mode. This is an
|
||||||
|
integer value between 0 and 255. 0 stops the fan, 255 makes
|
||||||
|
it run at full speed.
|
||||||
|
|
||||||
|
Both in PWM mode ('pwm1_mode' set to 1) and DC mode ('pwm1_mode' set to 0),
|
||||||
|
when current fan speed control mode is open-loop ('pwm1_enable' set to 1),
|
||||||
|
the fan speed is programmed by setting a value between 0 and 255 via 'pwm1'
|
||||||
|
entry (0 stops the fan, 255 makes it run at full speed). In closed-loop mode
|
||||||
|
('pwm1_enable' set to 2), the expected rotation speed in RPM can be passed to
|
||||||
|
the chip via 'fan1_target'. In closed-loop mode, the target speed is compared
|
||||||
|
with current speed (available via 'fan1_input') by the device and a feedback
|
||||||
|
is performed to match that target value. The fan speed value is computed
|
||||||
|
based on the parameters associated with the physical characteristics of the
|
||||||
|
system: a reference clock source frequency, a number of pulses per fan
|
||||||
|
revolution, etc.
|
||||||
|
|
||||||
|
Note that the driver will update its values at most once per second.

|
* resolution, a thermal alarm output (Tout), and user-defined minimum

|
* and maximum temperature thresholds (TH and TL).
|

|

|

|
* The DS1625, DS1631, DS1721, and DS1731 are pin compatible with the DS1621

|

|
*
|

|
* Since the DS1621 was the first chipset supported by this driver,
|
||||||
|
* most comments will refer to this chipset, but are actually general
