dt-bindings:iio:accel:bosch,bma180: txt to yaml format conversion. 



One question in here is whether we want to constrain the number of
interrupts.  Some parts definitely only have 1 such pin, and others
2 pins but I can not find information on the bma254.

Oleksandr's email address is bouncing so I've listed myself as
maintainer for this binding until someone else steps up.

Required properties:



  - compatible : should be one of:

    "bosch,bma023"

    "bosch,bma150"

    "bosch,bma180"

    "bosch,bma250"

    "bosch,bma254"

    "bosch,smb380"

  - reg : the I2C address of the sensor

  - vdd-supply : regulator phandle connected to the VDD pin

  - vddio-supply : regulator phandle connected to the VDDIO pin



Optional properties:



  - interrupts : interrupt mapping for GPIO IRQ, it should by configured with

		flags IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING

		For the bma250 the first interrupt listed must be the one

		connected to the INT1 pin, the second (optional) interrupt

		listed must be the one connected to the INT2 pin.



Example:



bma180@40 {

	compatible = "bosch,bma180";

	reg = <0x40>;

	interrupt-parent = <&gpio6>;

	interrupts = <18 (IRQ_TYPE_LEVEL_HIGH | IRQ_TYPE_EDGE_RISING)>;

};
