dt-bindings:iio:accel:fsl,mma8452: txt to yaml conversion. 



Simple binding so mostly straight forward to convert.
Original binding was unclear on how many interrupts there are.
The device has two such lines, whilst I believe the driver currently
only uses one at a time.  The binding should allow both to be specified.

triaxial accelerometer



Required properties:



  - compatible: should contain one of

    * "fsl,mma8451"

    * "fsl,mma8452"

    * "fsl,mma8453"

    * "fsl,mma8652"

    * "fsl,mma8653"

    * "fsl,fxls8471"



  - reg: the I2C address of the chip



Optional properties:



  - interrupts: interrupt mapping for GPIO IRQ



  - interrupt-names: should contain "INT1" and/or "INT2", the accelerometer's

		     interrupt line in use.



  - vdd-supply: phandle to the regulator that provides vdd power to the accelerometer.



  - vddio-supply: phandle to the regulator that provides vddio power to the accelerometer.



Example:



	mma8453fc@1d {

		compatible = "fsl,mma8453";

		reg = <0x1d>;

		interrupt-parent = <&gpio1>;

		interrupts = <5 0>;

		interrupt-names = "INT2";

	};
