ti,ina237 (on i2c bus)
Vendor: Texas Instruments
Description
TI INA237 Bidirectional Current and Power Monitor.
The <include/dt-bindings/sensor/ina237.h> file should be included
in the DeviceTree and it provides macros that can be used for
initializing the configuration registers.
Properties
Properties not inherited from the base binding file.

|
|
Value of the ADC configuration register (ADC conversion times,
averaging, operating mode and etc).
This property is required. |
|
|
Value of the configuration register
e.g shunt voltage and bus voltage ADC conversion
times and averaging, operating mode for INA230 or
delay for initial ADC conversion, shunt full scale range
for INA237.
This property is required. |
|
|
Value of Current LSB in milliamps. When set to 1mA,
Current is read in A, Bus Voltage in V, Shunt
Voltage in V, and Power in mW. Any other value
results in Current, Voltage, and Power registers
being read in counts.
This property is required. |
|
|
Shunt resistor value in milliohms
This property is required. |
|
|
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.
|
|
|
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.
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “ti,ina237” compatible.

|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
