commit b89710b upstream.

Currently there are only two modifiers for ultraviolet light: a generic
one for any ultraviolet light (IIO_MOD_LIGHT_UV) and one for deep
ultraviolet (IIO_MOD_LIGHT_DUV), which is also referred as ultraviolet
C (UV-C) band and covers short-wave ultraviolet.

There are still no modifiers for the long-wave and medium-wave
ultraviolet bands. These two bands are the main components used to
obtain the UV index on the Earth's surface.

Add modifiers for the ultraviolet A (UV-A) and ultraviolet B (UV-B)
bands.

commit 6f6c72a upstream.

The new modifiers should have added to the end of the enum, so they do
not affect the existing entries.

No modifiers were added since then, so they can be moved safely to the
end of the list.

Move IIO_MOD_LIGHT_UVA and IIO_MOD_LIGHT_UVB to the end of iio_modifier.

commit 3b82f43 upstream.

The Vishay VEMl6075 is a low power, 16-bit resolution UVA and UVB
light sensor with I2C interface and noise compensation (visible and
infrarred).

Every UV channel generates an output signal measured in counts per
integration period, where the integration time is configurable.

This driver adds support for both UV channels and the ultraviolet
index (UVI) inferred from them according to the device application note
with open-air (no teflon) coefficients.
