+Laser Sensor Device Tree Bindings.
+========================================
+
+Boards with the Laser Sensor connected to CCI shall have the following
+properties:
+
+Required node properties:
+       - cell-index: cci hardware core index
+    - compatible:
+               - "st,stmvl53l0" : STMiecroelectronics VL53L0 Laser sensor.
+       - reg : offset and length of the register set for the device
+       - qcom, cci-master: cci master the sensor connected to
+       - cam_cci-supply : cci voltage regulator used
+       - cam_laser-supply: laser sensor voltage regulator
+       - qcom,cam-vreg-name: voltage regulators name
+       - qcom, cam-vreg-min-voltage: specify minimum voltage level for
+               regulators used
+       - qcom, cam-vreg-max-voltage: specify maximum voltage level for
+               regulators used
+       - pinctrl-names : should specify the pin control groups followed by
+               the definition of each group
+       - gpios : should contain phandle to gpio controller node and array of
+               #gpio-cells specifying specific gpio (controller specific)
+       - qcom,gpio-req-tbl-num : contains index to gpios specific to the sensor
+       - qcom,gpio-req-tbl-flags : should contain direction of gpios present in
+               qcom,gpio-req-tbl-num property (in the same order)
+       - qcom,gpio-req-tbl-label : should contain name of gpios present in
+               qcom,gpio-req-tbl-num property (in the same order)
