Subject: [PATCH 0/4] iio: afe/rescale improvements

Hi Jonathan,

This patchset adds support for converting the "scale avail" list that
may be provided by the source drivers. It also implements the
.write_raw() callback.

These two features will later be used by the
(drivers/power/supply/ingenic-battery.c) driver, which will pick the
best scale possible for the battery's max voltage (it's already
implemented in there, but doesn't yet support iio-rescale being in the
middle).

As you suggested after my RFC I added support for a new
IIO_AVAIL_LIST_WITH_TYPE and it's been a perfect solution, so thank you
for that.

Cheers,
-Paul
