ti,tmag5273 (on i2c bus)

Vendor: Texas Instruments

Note

An implementation of a driver matching this compatible is available in drivers/sensor/ti/tmag5273/tmag5273.c.

Description

Texas Instruments Low-Power Linear 3D Hall-Effect Sensor with an I2C interface.

See the specification for the default I2C address.

The specification of the sensor can be found at:
  https://www.ti.com/lit/ds/symlink/tmag5273.pdf
  https://www.ti.com/lit/ds/symlink/tmag3001.pdf

  When setting the enum properties in a .dts or .dtsi file you may
  include tmag5273.h and use the macros defined there.

  Example:
  #include <zephyr/dt-bindings/sensor/tmag5273.h>

  tmag5273: tmag5273@0 {
    ...
    axis = <TMAG5273_DT_AXIS_XYZ>;
    range = <TMAG5273_DT_AXIS_RANGE_HIGH>;
  };

Properties not inherited from the base binding file.

Name	Type	Details
operation-mode	int	Sensor mode used if set to "active". Defaults to continuous sampling (TMAG5273_DT_OPER_MODE_CONTINUOUS). - 0 # TMAG5273_DT_OPER_MODE_CONTINUOUS (continuous) - 1 # TMAG5273_DT_OPER_MODE_STANDBY (standby) Legal values: 0, 1

temperature	boolean	Select for temperature measurement.
range	int	XYZ-measurement range for magnetic-field value. Defaults to lower range (higher resolution; TMAG5273_DT_AXIS_RANGE_LOW). - 0 # TMAG5273_DT_AXIS_RANGE_LOW (+/-40 mT (TMAG5273A1) or +/-133 mT (TMAG5273A2)) - 1 # TMAG5273_DT_AXIS_RANGE_HIGH (+/-80 mT (TMAG5273A1) or +/-266 mT (TMAG5273A2)) - 2 # TMAG5273_DT_AXIS_RANGE_RUNTIME (@runtime (initial value is: "high")) Default value: 1 Legal values: 0, 1, 2
int-gpios	phandle-array	The INT signal connection. The signal is active-low as produced by the sensor. Either used for interrupt signaling, or triggering a conversion.
temperature-coefficient	int	Selects the magnet temperature coefficient. Defaults to none (TMAG5273_DT_TEMP_COEFF_NONE). - 0 # TMAG5273_DT_TEMP_COEFF_NONE (none) - 1 # TMAG5273_DT_TEMP_COEFF_NDBFE (0.12 %/deg C (NdBFe)) - 2 # TMAG5273_DT_TEMP_COEFF_CERAMIC (0.2 %/deg C (Ceramic)) Ignored if temperature is not measured. Legal values: 0, 1, 2
trigger-conversion-via-int	boolean	Selects initiation of a single conversion based on a trigger via the INT-pin if enabled, and via I2C-command if disabled. Used in "standby"-, "wakeup-and-sleep"- and "sleep"-mode. Using I2C-conversion trigger may result in (handled) I2C-errors.
angle-magnitude-axis	int	Enables angle calculation, magnetic gain, and offset corrections between two selected magnetic channels. Defaults to no additional calculations (TMAG5273_DT_ANGLE_MAG_NONE). - 0 # TMAG5273_DT_ANGLE_MAG_NONE (deactivated) - 1 # TMAG5273_DT_ANGLE_MAG_XY (x/y) - 2 # TMAG5273_DT_ANGLE_MAG_YZ (y/z) - 3 # TMAG5273_DT_ANGLE_MAG_XZ (x/z) - 4 # TMAG5273_DT_ANGLE_MAG_RUNTIME (@runtime (initial value is: "deactivated")) Legal values: 0, 1, 2, 3, 4
ch-mag-gain-correction	int	Channel for the magnitude gain correction. Defaults to 1st channel. - 0 # TMAG5273_DT_CORRECTION_CH_1 (1st channel) - 1 # TMAG5273_DT_CORRECTION_CH_2 (2nd channel) Only active if angle-magnitude-calculation is active. Legal values: 0, 1
average-mode	int	Enables additional sampling of the sensor data to reduce the noise effect (or to increase resolution). Note that averaging will influence the output data rate. Defaults to 2x averaging (TMAG5273_DT_AVERAGING_2X). - 0 # TMAG5273_DT_AVERAGING_NONE (10.0-kSPS (3-axes) or 20-kSPS (1 axis)) - 1 # TMAG5273_DT_AVERAGING_2X (5.7-kSPS (3-axes) or 13.3-kSPS (1 axis)) - 2 # TMAG5273_DT_AVERAGING_4X (3.1-kSPS (3-axes) or 8.0-kSPS (1 axis)) - 3 # TMAG5273_DT_AVERAGING_8X (1.6-kSPS (3-axes) or 4.4-kSPS (1 axis)) - 4 # TMAG5273_DT_AVERAGING_16X (0.8-kSPS (3-axes) or 2.4-kSPS (1 axis)) - 5 # TMAG5273_DT_AVERAGING_32X (0.4-kSPS (3-axes) or 1.2-kSPS (1 axis)) Default value: 1 Legal values: 0, 1, 2, 3, 4, 5
crc-enabled	boolean	Activate I2C CRC byte to be sent.
low-noise	boolean	Select low-noise mode when enabled, and low-power mode when disabled.
ignore-diag-fail	boolean	Ignore detected diagnostic fail. According to the manual, this should be done if VCC < 2.3V.
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.
