Add POWER_SUPPLY_TYPE_BMS for the hardware chip or module which
monitors battery for state of charge and other properties.
BMS will register itself as a separate power supply of type BMS.
The charger will register the battery power supply and pull BMS data
from the BMS power supply if it exists.

Currently, we enable the timer hardware and unmask its interrupt in
the set_next_event callback. However, during hotplug, this callback
can be called after the timer is already supposed to be disabled.
Since the timer will be completely turned back on by set_next_event,
we will soon receive an interrupt, potentially causing us to wake up
from hotplug.
Instead, continue unmasking the interrupt when set_next_event is
called, but only enable the timer hardware in the set_mode callback.
This means that, once arch_timer_disable is called, we are guaranteed
to not receive more timer interrupts until the cpu is intentionally
hotplugged back in.

Since the overhead involved may differ based on the frequencies
being switched between, record both the start and the end frequencies

Enabling SCHED_HRTICK currently results in rq->lock recursion and a hard
hang at bootup. Essentially try_to_wakeup() grabs rq->lock and tries
arming a hrtimer via hrtimer_restart(), which deep down tries waking up
ksoftirqd, which leads to a recursive call to try_to_wakeup() and thus
attempt to take rq->lock recursively!!
This is fixed by having scheduler queue hrtimer via
__hrtimer_start_range_ns() which avoids waking up ksoftirqd.

(cherry picked from commit 4ca1d04ea0bdc225cc7db302172f3375a63f44de)
When v4l2 streamon() is called the framework moves to streamon state,
after queueing the buffer. A state check is performed during dqbuf().
Sometimes when dqbuf() is called streamon() function has not completed
setting the state transisiton flag. This results in failure to dqbuf() as
the framework has not moved to streamon. This patch adds a mutex
around state transitions and dqbuf() calls.

Currently we enable the timer and unmask the interrupt
before setting the TVAL.
(in commit 9c642ecd6b71bb068c8a931285dc1dce043b137c)
This could cause a regression by opening a window
where TVAL can be negative (from a previous timer trigger)
and the interrupt unmasked, which would lead to an
immediate trigger, before TVAL is updated with the new value.
We need to set the TVAL after unmasking the interrupt, but
before enabling the timer.

valid. current->active_mm can also be used for non-anonymous processes
as it would be equivalent to current->mm.

Errors returned from regulator_check_drms() are not treated as fatal
by any of its callers, nor are they passed up through exported
regulator APIs. Instead, these errors are used to indicate that a
regulator does not support multiple current modes.
For example, the exported regulator_set_optimum_mode() API explicitly
discards errors from regulator_check_drms() and returns success anyway
since there is no work to be done to change modes.
To prevent errors from being printed in these cases, downgrade the
rdev_err() prints in regulator_check_drms() to rdev_dbg() prints.

Currently, the default and the recommended value for GUSB3PIPECTL[21:19]
in the RTL is 3'b100 or 32 consecutive errors. Based on analysis and
experiments in the lab, it is found that there is a relatively low
probability of getting 32 consecutive word errors in the presence of
random recovered noise (during electrical idle). This can delay the entry
to a low power state such that for applications where the link stays in a
non-U0 state for a short duration (< 1 microsecond), the local PHY does
not enter the low power state prior to receiving a potential LFPS wakeup.
This causes the PHY CDR (Clock and Data Recovery) operation to be unstable
for some Synopsys PHYs.
The proposal now is to change the default and the recommended value for
GUSB3PIPECTL[21:19] in the RTL from 3'b100 to a minimum of 3'b001. Perform
the same in software for controllers prior to 2.30a revision.
