power: android battery: add generic android battery driver

Add a generic battery power supply and glue logic for talking to the
board battery driver.  This driver handles common chores such as:

* periodic battery level and health monitoring
* kernel log reporting and other debugging features for key
  properties provided by different charger, fuel gauge, etc.
  components
* ensure properties such as battery health are made available to
  userspace
* common processing for board-level battery/case temperature sensors
  and policy for charging status based on battery health

Based on work by himihee.seo@samsung.com, ms925.kim@samsung.com, and
joshua.chang@samsung.com.

sync: add internal refcounting to fences

If a fence is released while a timeline that one of it's pts is on is being
signaled, it is possible for that fence to be deleted before it is signaled.
This patch adds a refcount for internal references such as signaled pt
processing.

leds: triggers: send uevent when changing triggers

Some triggers create sysfs files when they are enabled.  Send a uevent
"change" notification whenever the trigger is changed to allow userspace
processes such as udev to modify permissions on the new files.

sync: add reference counting to timelines

If a timeline is destroyed while fences still hold pts on it, the reworked
fence release handler can cause the timeline to be freed before all it's points
are freed.

PM: Add watchdog to catch lockup during device resume

Refactor the dpm suspend watchdog code and add watchdogs
on resume too. The dpm wachdog prints the stack trace and
reboots the system if a device takes more than 12 seconds
to suspend or resume.

alarmtimer: implement minimum alarm interval for allowing suspend

alarmtimer suspend return -EBUSY if the next alarm will fire in less
than 2 seconds.  This allows one RTC seconds tick to occur subsequent
to this check before the alarm wakeup time is set, ensuring the wakeup
time is still in the future (assuming the RTC does not tick one more
second prior to setting the alarm).  If suspend is rejected, hold a
wakeup source for 2 seconds to process the alarm prior to reattempting
suspend.

ARM: sched_clock: update epoch_cyc on resume

Many clocks that are used to provide sched_clock will reset during
suspend.  If read_sched_clock returns 0 after suspend, sched_clock will
appear to jump forward.  This patch resets cd.epoch_cyc to the current
value of read_sched_clock during resume, which causes sched_clock() just
after suspend to return the same value as sched_clock() just before
suspend.

In addition, during the window where epoch_ns has been updated before
suspend, but epoch_cyc has not been updated after suspend, it is unknown
whether the clock has reset or not, and sched_clock() could return a
bogus value.  Add a suspended flag, and return the pre-suspend epoch_ns
value during this period.

The new behavior is triggered by calling setup_sched_clock_needs_suspend
instead of setup_sched_clock.
