| D | bh1770glc.txt | 16 BH1770GLC and SFH7770 are combined ambient light and proximity sensors.
17 ALS and proximity parts operates on their own, but they shares common I2C
19 but ALS side results are used to estimate reliability of the proximity sensor.
24 Proximity part contains IR-led driver up to 3 IR leds. The chip measures
25 amount of reflected IR light and produces proximity result. Resolution is
27 reliability of the proximity results. Thus ALS is always running while
28 proximity detection is needed.
31 Proximity low interrupt doesn't exists in the chip. This is simulated
32 by using a delayed work. As long as there is proximity threshold above
33 interrupts the delayed work is pushed forward. So, when proximity level goes

38 Proximity side is little bit simpler. There is no need for complex conversions.
88 RO - measured proximity value
95 RW - enable / disable proximity - uses counting logic
96 1 enables the proximity
97 0 disables the proximity
101 values: 0 or prox0_sensor_range value. 0 means no proximity,
102 1023 means proximity. This causes minimal number of interrupts.
111 RW - threshold level which trigs proximity events.
