Subject: [PATCH 0/2] Introduce new iio resolution standard attribute

This patch introduces a new IIO standard attribute to set the bit
resolution of the data *_raw readings dynamically using sysfs.

The VCNL4040/4200 proximity/ambient light sensors support 12-bit
(default) and 16-bit ADC resolutions. This can be dynamically changed,
so to support this with the standard iio channel configuration a new iio
attribute should be added.

The VCNL4040 devices will use this for setting proximity high definition
(16-bit resolution).
