* AMS TAOS TSL2563 ambient light sensor
Required properties:
- compatible : should be "amstaos,tsl2563"
- reg : the I2C address of the sensor
Optional properties:
- amstaos,cover-comp-gain : integer used as multiplier for gain
compensation (default = 1)
Example:
tsl2563@29 {
compatible = "amstaos,tsl2563";
reg = <0x29>;
amstaos,cover-comp-gain = <16>;
};
