5Description:
6		This sensor has an automatic gain control (agc) loop
7		which sets the analog signal levels at an optimum
8		level by controlling programmable gain amplifiers. The
9		criteria for optimal gain is determined by the sensor.
10
11		Return the actual gain value as an integer in [0; 65536]
12		range when read from.
13
14		The agc gain read when measuring crosstalk shall be
15		written into in_proximity0_agc_gain_bias.

23Description:
24		The sensor is able to perform correction of distance
25		measurements due to changing temperature and ambient
26		light conditions. It can be programmed to correct for
27		a second order error polynomial.
28
29		Phase data has to be collected when temperature and
30		ambient light are modulated independently.
31
32		Then a least squares curve fit to a second order
33		polynomial has to be generated from the data. The
34		resultant curves have the form ax^2 + bx + c.
35
36		From those two curves, a and b coefficients shall be
37		stored in in_proximity0_calib_phase_temp_a and
38		in_proximity0_calib_phase_temp_b for temperature and
39		in in_proximity0_calib_phase_light_a and
40		in_proximity0_calib_phase_light_b for ambient light.
41
42		Those values must be integer in [0; 8355840] range.
43
44		Finally, the c constant is set by the sensor
45		internally.
46
47		The value stored in sensor is displayed when read from.
