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:
+ This entry configures the input dynamic power path management voltage of
+ bq24257-type charger devices. Once the supply drops to the configured
+ voltage, the input current limit is reduced down to prevent the further
+ drop of the supply. When the IC enters this mode, the charge current is
+ lower than the set value. See device datasheet for details.

+Description:
+ This entry allows enabling the high-impedance mode of bq24257-type
+ charger devices. If enabled, it places the charger IC into low power
+ standby mode with the switch mode controller disabled. When disabled,
+ the charger operates normally. See device datasheet for details.

+Description:
+ This entry allows enabling the sysoff mode of bq24257-type charger
+ devices. If enabled and the input is removed, the internal battery FET
+ is turned off in order to reduce the leakage from the BAT pin to less
+ than 1uA. Note that on some devices/systems this disconnects the battery
+ from the system. See device datasheet for details.
