* Sharp GP2AP020A00F I2C Proximity/ALS sensor
The proximity detector sensor requires power supply
for its built-in led. It is also defined by this binding.
Required properties:
- compatible : should be "sharp,gp2ap020a00f"
- reg : the I2C slave address of the light sensor
- interrupts : interrupt specifier for the sole interrupt generated
by the device
- vled-supply : VLED power supply, as covered in ../regulator/regulator.txt
Example:
gp2ap020a00f@39 {
compatible = "sharp,gp2ap020a00f";
reg = <0x39>;
interrupts = <2 0>;
vled-supply = <...>;
};
