       https://lore.kernel.org/linux-iio/20201013153431.000052c9@huawei.com/
       - remove Unit from tittle
       - reword interrupts description
       - drop interrupt-name description
       - add spi example and bindings
       - remove vddxx from required list

-* NXP FXAS21002C Gyroscope device tree bindings
-
-http://www.nxp.com/products/sensors/gyroscopes/3-axis-digital-gyroscope:FXAS21002C
-
-Required properties:
-  - compatible : should be "nxp,fxas21002c"
-  - reg : the I2C address of the sensor or SPI chip select number for the
-          device.
-  - vdd-supply: phandle to the regulator that provides power to the sensor.
-  - vddio-supply: phandle to the regulator that provides power to the bus.
-
-Optional properties:
-  - reset-gpios : gpio used to reset the device, see gpio/gpio.txt
-  - interrupts : device support 2 interrupts, INT1 and INT2,
-                 the interrupts can be triggered on rising or falling edges.
-                 See interrupt-controller/interrupts.txt
-  - interrupt-names: should contain "INT1" or "INT2", the gyroscope interrupt
-                     line in use.
-  - drive-open-drain: the interrupt/data ready line will be configured
-                      as open drain, which is useful if several sensors share
-                      the same interrupt line. This is a boolean property.
-                      (This binding is taken from pinctrl/pinctrl-bindings.txt)
-
-Example:
-
-gyroscope@20 {
-	compatible = "nxp,fxas21002c";
-	reg = <0x20>;
-	vdd-supply = <&reg_peri_3p15v>;
-	vddio-supply = <&reg_peri_3p15v>;
-};
