lm77 (on i2c bus)

Vendor: Generic or vendor-independent

Description

LM77 digital temperature sensor

Properties

Properties not inherited from the base binding file.

Name

Type

Details

int-gpios

phandle-array

Identifies the INT signal, which is active-low open drain by default
when produced by the sensor.

int-inverted

boolean

When present, the polarity on the INT signal is inverted (active-high).

tcrita-inverted

boolean

When present, the polarity on the T_CRIT_A signal is inverted
(active-high).

enable-fault-queue

boolean

When present, the fault queue is enabled. The fault queue allows up to 4
faults to prevent false INT/T_CRIT_A tripping when the LM77 is used in
noisy environments.

friendly-name

string

Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
