Description
|
||||
-----------
|
||||
|

The ISL28022 is a power monitor with I2C interface. The device monitors
|
||||
voltage, current via shunt resistor and calculated power.
|
||||
|
||||
Usage Notes
|
||||
-----------
|
||||
|
||||
This driver does not auto-detect devices. You will have to instantiate the
|
||||
device explicitly. Please see Documentation/i2c/instantiating-devices.rst for
|
||||
details.
|
||||
|
||||
The shunt value in micro-ohms, shunt voltage range and averaging can be set
|
||||
with device properties.
|
||||
Please refer to the Documentation/devicetree/bindings/hwmon/isl,isl28022.yaml
|
||||
for bindings if the device tree is used.
|
||||
|
||||
The driver supports only shunt and bus continuous ADC mode at 15bit resolution.
|
||||
Averaging can be set from 1 to 128 samples (power of 2) on both channels.
|
||||
Shunt voltage range of 40, 80, 160 or 320mV is allowed
|
||||
The bus voltage range is 60V fixed.
|
||||

||||

Description
|

-----------
|
||||
|
||||
The NCT7363Y is a fan controller which provides up to 16 independent
|
||||
FAN input monitors, and up to 16 independent PWM outputs with SMBus interface.

Currently, the driver supports the following features:

|

fanX_input provide current fan rotation value in RPM
|

fanX_alarm report fan low speed real status
|
||||
fanX_min get or set fan count threshold
|
||||
|
||||
pwmX get or set PWM fan control value.

driver will try to read the STATUS register after each failed

register check. This read may fail, but it will put the chip into a

known state.
|

|

PMBUS_NO_WRITE_PROTECT
|
||||
|
||||
Some PMBus chips respond with invalid data when reading the WRITE_PROTECT
|
||||
register. For such chips, this flag should be set so that the PMBus core
|
||||
driver doesn't use the WRITE_PROTECT command to determine its behavior.
|
||||
|
||||
PMBUS_USE_COEFFICIENTS_CMD
|
||||
|

When this flag is set the PMBus core driver will use the COEFFICIENTS
|
||||
register to initialize the coefficients for the direct mode format.

---------------------

The SCH5627 allows for partially controlling the fan speed. If a temperature

channel excedes tempX_max, all fans are forced to maximum speed. The same is not
