[PATCH 0/2] iio: Fix integration time unit

[Matti Vaittinen]

[-- Attachment #1: Type: text/plain, Size: 946 bytes --]

The recently introduced BU27034 used micro-seconds as units for
integration time. So did the GTS-helpers.

The IIO ABI mandates using seconds. This series fixes integration times
for the BU27034 ALS driver and the GTS-helpers.

[PATCH 2/2] iio: gts-helpers: fix integration time units

[Matti Vaittinen]

[-- Attachment #1: Type: text/plain, Size: 3306 bytes --]

The IIO ABI mandates expressing integration times in seconds. The GTS
helper errorneously uses micro seconds in integration_times_available.
Fix this by converting the lists to IIO_VAL_INT_PLUS_MICRO.

Grumble.

If nothing else comes up I'll tidy that stray line up when applying.

Note that these will need to wait for after rc1 now so my fixes branch
has moved on to include the code being fixed.

Oh. I wonder how things like this tend to slip-in. Maybe I should change 
my password, it must be someone else has cracked my it and is typing 
these in at night while I am sleeping ^_^;

Well, that's Ok. Please, let me know if you want me to rebase to rc1 and 
respin the series.

No need as not much changed around these (not I'm not at rc1 yet, but
char-misc-linus now includes these so I rebased on that)

Applied to the fixes-togreg branch of iio.git with fixes tags added now
the commits are upstream.

Thanks,
