Subject: [PATCH 0/7] hwmon: iio: Add alarm support

Add alarm support for IIO HWMONs as well as the minimum/maximum
thresholds. This involves the creation of two new in-kernel IIO APIs to
set the thresholds and be notified of events.

I think this should probably go through the iio tree given the amount of
IIO stuff it touches.


Sean Anderson (7):
  math64: Add div64_s64_rem
  iio: inkern: Add API for reading/writing events
  iio: Add in-kernel API for events
  hwmon: iio: Refactor scale calculation into helper
  hwmon: iio: Add helper function for creating attributes
  hwmon: iio: Add min/max support
  hwmon: iio: Add alarm support
