Additionally, this "PGO" pin - is it necessary for a driver to know what state it is in to function correctly? If so, can the information about which state it is in be gathered from i2c? Should there also be an optional pgo-gpios property for the scenario where it is not tied, but set by a GPIO, if that is even possible. > Signed-off-by: Aditya Dutt <duttaditya18@gmail.com> > --- > .../bindings/iio/position/ams,as5600.yaml | 42 +++++++++++++++++++ > 1 file changed, 42 insertions(+) > create mode 100644 Documentation/devicetree/bindings/iio/position/ams,as5600.yaml > > diff --git a/Documentation/devicetree/bindings/iio/position/ams,as5600.yaml b/Documentation/devicetree/bindings/iio/position/ams,as5600.yaml > new file mode 100644 > index 000000000000..d4c92dd41dd6 > --- /dev/null > +++ b/Documentation/devicetree/bindings/iio/position/ams,as5600.yaml > @@ -0,0 +1,42 @@ > +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) > +%YAML 1.2 > +--- > +$id: http://devicetree.org/schemas/iio/position/ams,as5600.yaml# > +$schema: http://devicetree.org/meta-schemas/core.yaml# > + > +title: ams AS5600 Position Sensor > + > +maintainers: > + - Aditya Dutt <duttaditya18@gmail.com> > + > +description: | > + 12-Bit Programmable Contactless Potentiometer > + > +properties: > + compatible: > + enum: > + - ams,as5600 blank line here please. > + reg: > + maxItems: 1 > + description: | > + The I2C register address of the device.

The AS5600 is a Hall-based rotary magnetic position sensor using planar sensors that convert the magnetic field component perpendicular to the surface of the chip into a voltage, or a numerical value available through i2c. Add dt-bindings for the sensor.
