Subject: [PATCH v3 2/3] dt-bindings: iio: magnetometer: add ti tmag5273 documentation file
Add bindings for TI TMAG5273.
Signed-off-by: Gerald Loacker <gerald.loacker@...fvision.net>
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
Changes in v3:
- dropped quotes from strings
Changes in v2:
- Removed nodename
- Changed angle-enable to angle-measurement and used strings
- Added interrupts
- Removed vcc-supply from required properties
- Changed i2c-0 to i2c in examples

+title: TI TMAG5273 Low-Power Linear 3D Hall-Effect Sensor
+
+maintainers:
+ - Gerald Loacker <gerald.loacker@...fvision.net>
+
+description:
+ The TI TMAG5273 is a low-power linear 3D Hall-effect sensor. This device
+ integrates three independent Hall-effect sensors in the X, Y, and Z axes.
+ The device has an integrated temperature sensor available. The TMAG5273
+ can be configured through the I2C interface to enable any combination of
+ magnetic axes and temperature measurements. An integrated angle calculation
+ engine (CORDIC) provides full 360° angular position information for both
+ on-axis and off-axis angle measurement topologies. The angle calculation is
+ performed using two user-selected magnetic axes.

+ The low active interrupt can be configured to be fixed width or latched.
+ Interrupt events can be configured to be generated from magnetic
+ thresholds or when a conversion is completed.
