		STM VL53L0X Time-of-Flight ranging and gesture detection sensor driver

		Description:

		The VL53L0X is a new generation Time-of-Flight
		(ToF) laser-ranging module housed in the
		smallest package on the market today, providing
		accurate distance measurement whatever the
		target reflectances unlike conventional
		technologies. It can measure absolute distances
		up to 2m, setting a new benchmark in ranging
		performance levels, opening the door to various
		new applications.
		The VL53L0X integrates a leading-edge SPAD
		array (Single Photon Avalanche Diodes) and
		embeds ST’s second generation FlightSenseTM
		patented technology.
		The VL53L0X’s 940 nm VCSEL emitter (Vertical
		Cavity Surface-Emitting Laser), is totally invisible
		to the human eye, coupled with internal physical
		infrared filters, it enables longer ranging
		distances, higher immunity to ambient light, and
		better robustness to cover glass optical crosstalk.

		Required properties:

		- compatible : Should be "st,stmvl53l0".
		- reg : i2c slave address of the device.

		Example:
		i2c@f9925000 {
		vl53l0x@52 {
		compatible = "st,stmvl53l0";
		reg = <0x52>;
		};
		};
