-* UPISEMI us5182d I2C ALS and Proximity sensor
-
-Required properties:
-- compatible: must be "upisemi,usd5182"
-- reg: the I2C address of the device
-
-Optional properties:
-- upisemi,glass-coef: glass attenuation factor - compensation factor of
- resolution 1000 for material transmittance.
-
-- upisemi,dark-ths: array of 8 elements containing 16-bit thresholds (adc
- counts) corresponding to every scale.
-
-- upisemi,upper-dark-gain: 8-bit dark gain compensation factor(4 int and 4
- fractional bits - Q4.4) applied when light > threshold
-
-- upisemi,lower-dark-gain: 8-bit dark gain compensation factor(4 int and 4
- fractional bits - Q4.4) applied when light < threshold
-
-- upisemi,continuous: This chip has two power modes: one-shot (chip takes one
- measurement and then shuts itself down) and continuous (
- chip takes continuous measurements). The one-shot mode is
- more power-friendly but the continuous mode may be more
- reliable. If this property is specified the continuous
- mode will be used instead of the default one-shot one for
- raw reads.
-
-If the optional properties are not specified these factors will default to the
-values in the below example.
-The glass-coef defaults to no compensation for the covering material.
-The threshold array defaults to experimental values that work with US5182D
-sensor on evaluation board - roughly between 12-32 lux.
-There will be no dark-gain compensation by default when ALS > thresh
-(0 * dark-gain), and a 1.35 compensation factor when ALS < thresh.
-
-Example:
-
- usd5182@39 {
- compatible = "upisemi,usd5182";
- reg = <0x39>;
- upisemi,glass-coef = < 1000 >;
- upisemi,dark-ths = /bits/ 16 <170 200 512 512 800 2000 4000 8000>;
- upisemi,upper-dark-gain = /bits/ 8 <0x00>;
- upisemi,lower-dark-gain = /bits/ 8 <0x16>;
- };
