The AMS AS7331 UV light sensor measures three ultraviolet bands (UVA,
UVB and UVC, also known as deep UV or DUV) as well as temperature.

This device is practically identical to the AMS AS73211 XYZ True Color
sensor that is already supported by the iio subsystem, except for the
photodiodes used to aquire the desired light wavelengths.

In order to reuse code and reduce maintenance load, this series extends
the AS73211 driver to support the AS7331 as well.

Note that the UVA and UVB light modifiers have not been merged into the
mainline kernel yet, but they are already available in Greg's char-misc
git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-next branch.

The original device AS73211 supported by the driver could only be tested
briefly due to the lack of hardware. Instead, the i2c-stub module has
been used to make sure that the driver registers the iio device properly
and the attributes exported to sysfs are correct. Some basic register
assignments reported the expected intensity scales and in principle
nothing else should have been affected by the modifications in the code.
