ti,ina230 (on i2c bus)

Description

TI INA230 and INA231 Bidirectional Current and Power Monitor.
The <zephyr/dt-bindings/sensor/ina230.h> file should be included in the
DeviceTree and it provides macro that can be used for initializing the
configuration register.

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`mask`	`int`	Mask register, default matches the power-on reset value
`alert-limit`	`int`	Alert register, default matches the power-on reset value
`config`	`int`	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.
`current-lsb-microamps`	`int`	This value should be selected so that measurement resolution is maximized, that is: current-lsb(A) = maximum expected current(A) / 2^15 (sensor has 15 bits). For example, if maximum expected current is 15A: current-lsb(A) = 15A / 2^15 ~= 457uA Rounded values may be used for convenience, e.g. 500uA/LSB or 1mA/LSB while keeping a good measurement resolution. The units are in uA/LSB so that low maximum currents can be measured with enough resolution. This property is required.
`rshunt-milliohms`	`int`	Shunt resistor value in milliohms This property is required.
`alert-gpios`	`phandle-array`	Alert pin
`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.

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,ina230” compatible.

Name	Type	Details
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`wakeup-source`	`boolean`	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`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
