These changes are the raw update to linux-4.4.6-rt14. Kernel sources
are taken from kernel.org, and rt patch from the rt wiki download page. During the rebasing, the following patch collided: Force tick interrupt and get rid of softirq magic(I70131fb85). Collisions have been removed because its logic was found on the source already. Change-Id: I7f57a4081d9deaa0d9ccfc41a6c8daccdee3b769 Signed-off-by: José Pekkarinen <jose.pekkarinen@nokia.com>

+Description:
+ Program sensor type for threshold detector inputs.
+ Could be either "GND-Open" or "Supply-Open" mode. Y is a
+ threshold detector input channel. Channels 0..7, 8..15, 16..23
+ and 24..31 has common sensor types.

+Contact: source@cogentembedded.com
+Description:
+ Channel Y low voltage threshold. If sensor input voltage goes lower then
+ this value then the threshold falling event is pushed.
+ Depending on in_voltageY_sensing_mode the low voltage threshold
+ is separately set for "GND-Open" and "Supply-Open" modes.
+ Channels 0..31 have common low threshold values, but could have different
+ sensing_modes.
+ The low voltage threshold range is between 2..21V.
+ Hysteresis between low and high thresholds can not be lower then 2 and
+ can not be odd.
+ If falling threshold results hysteresis to odd value then rising
+ threshold is automatically subtracted by one.

+Description:
+ Channel Y high voltage threshold. If sensor input voltage goes higher then
+ this value then the threshold rising event is pushed.
+ Depending on in_voltageY_sensing_mode the high voltage threshold
+ is separately set for "GND-Open" and "Supply-Open" modes.
+ Channels 0..31 have common high threshold values, but could have different
+ sensing_modes.
+ The high voltage threshold range is between 3..22V.
+ Hysteresis between low and high thresholds can not be lower then 2 and
+ can not be odd.
+ If rising threshold results hysteresis to odd value then falling
+ threshold is automatically appended by one.
