staging: iio: cm3217: add optional value in DT.
Add below optional value can be overrid by DT for project. If no add in DT will load default value. 1)integration-time. Default:"480000" 2)max-range. Default:"78643.2" 3)resolution. Default:"307" 4)power-consumed. Default:"1670" Bug 1496947 Change-Id: I8718bf5636042bc801574c8e4177a12e5a948540 Signed-off-by: steven <skao@nvidia.com> Signed-off-by: Sri Krishna chowdary <schowdary@nvidia.com> Reviewed-on: http://git-master/r/395755 Reviewed-on: http://git-master/r/411415 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Pritesh Raithatha <praithatha@nvidia.com> Reviewed-by: Mitch Luban <mluban@nvidia.com>

+* Capella CM3217 ambient light sensor
+
+Required properties:
+- compatible: must be "capella,cm3217"
+- reg: i2c address of the device. It should be 0x10.
+- vdd-supply: regulator supply for the chip
+
+Optional propertied:
+- illuminance,integration-time: minimum sampling period in nano seconds.
+ default: ""480000""
+- illuminance,max-range: maximum range of this sensor's value in SI units.
+ default: "78643.2"
+- illuminance,resolution: conversion factor from sensor raw units to lux.
+ default: "307"
+- illuminance,power-consumed: rough estimate of this sensor's power consumption in mA.
+ default: "1670"
+
+Example:
+ cm3217@10 {
+ compatible = "capella,cm3217";
+ reg = <0x10>;
+ vdd-supply = <&palmas_smps9>;
+ illuminance,integration-time = "480000";
+ illuminance,max-range = "78643.2";
+ illuminance,resolution = "7675";
+ illuminance,power-consumed = "1670"; /* milli Watt */
+ };
