[PATCH 0/3] iio: Fix integration time units for iio-gts

[Matti Vaittinen]

The newly added iio-gts-helper (gain time scale helper) errorneously
reports available integration times as micro seconds. The same mistake
is in newly added BU27034 light sensor driver. Fix these by adding new
IIO_VAL type, IIO_VAL_INT_MICRO - which can be used for micro <unit>
values where the integer part is zero.

NOTE:
I did not have the time to test the gts-helpers with integration times
which are greater than 1 second. Currently there is no other in-tree users
besides the bu27034, which does always use integration times smaller
than 1 second. When greater than 1 second times are needed, this needs
to be revised. (Or, when the devm_* interface kunit test support gets
added). Right now this should be a quick fix to integration time
handling before the bug manifests itself in the user-space).

I am planning to test (and re-work if needed) the gts-helpers available
integration time list for > 1Sec times - but I most probably don't have
the time for that during this or next week. (Don't know about the
weekend though - but probably not.)
