iio: light: vcnl4000: Add oversampling_ratio for 4040/4200

Browse source

Add the proximity multi pulse (PS_MPS) as oversampling_ratio.
Instead of one single pulse per every defined time frame, one can
program2, 4, or even 8 pulses. This leads to a longer IRED on-time
for each proximity measurement value, which also results in a higher
detection range.

Add read/write attribute for proximity oversampling-ratio and read
attribute for available oversampling-ratio.
This is supported for vcnl4040 and vcnl4200.
