[PATCH v3 00/11] iio: adc: ti-ads1015: fixes, cleanups, and threshold event support

[Akinobu Mita <akinobu.mita@gmail.com>]

This series contains some fixes and cleanups, and a threshold event support
for ti-ads1015 driver.

The first six patches are bug fixes, next four are cleanups, and the last
one adds support threshold event.

Changes from v2 (All changes are done in the last patch)
- Add an error checking for conv register read in interrupt handler
- Fix comparator polarity field setting in config register

Changes from v1
- Split the patch "enable conversion when CONFIG_PM is not set" into a pure
  fix and a cleanup
- Add new patch "don't return invalid value from buffer setup callbacks"
- Add new patch "add adequate wait time to get correct conversion"
- Support traditional comparator mode in addition to window comparator mode,
  add a comment for default threshold settings, and allow setting the state
  that has already been set in threshold event support patch
