The power supply type property is varying as the external power
supply changes. It is not a constant.

Add the charger status change interrupt support, it will report
the power supply changed event.
This interrupt is generated by one of the conditions as below:
- the state machine jumps out of or into the EOC state
- the CHGIN input voltage goes out of or into the valid range.
- the battery temperature goes out of or into the valid range.
- the PRECHARGE time-out occurs.
- the total charge time-out occurs.

When get the property, first check the charger state machine,
then check the status bit to decide what value is assigned to
the corresponding property.
Retain the SUSCHG bit of REG 0x71 when configure the timers to
avoid losting the charger suspending info after boot.

Remove "battery_temperature" member, it is redundant, it is the
hardware's responsibility to handle TH pin properly.
It is unnecessary to use the dt property to check if there is
a battery temperature monitor or not.

Since the act8945a_charger is regarded as a sub-device, all properties will
be assigned to its own device node. All properties can be achieved from its
own node, instead of from its parent device.

When the charger is missing (disconnected), it is safe to assume that
the charger chip is no charging.
This is especially relevant when a status GPIO is present and the
charger is getting disconnected. bq24735_charger_is_charging will be
triggered due to the interrupt then, it will attempt to read whether it
is charging through i2c, which will fail as the charger is disconnected.
This also fixes that specific issue.

Power Supply Fixes for 4.8 cycle

alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.
The workqueue "monitor_wqueue" is used to monitor the battery
status. It has been identity converted.
It queues multiple work items viz &di->monitor_work,
&di->set_charged_work, which require execution ordering.
Hence, alloc_workqueue has been used to replace the
deprecated create_singlethread_workqueue instance.
WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure.

The workqueue "wq" is used for handling battery related tasks.
It has a single work item viz &mb->update and hence it doesn't require
execution ordering. Hence, alloc_workqueue has been used to replace the
deprecated create_singlethread_workqueue instance.
The WQ_MEM_RECLAIM flag has been set to ensure forward progress under

Since there is a single work item, explicit concurrency
limit is unnecessary here.

The workqueue "monitor_wqueue" is used to monitor the PMIC battery status.
It queues a single work item (pbi->monitor_battery) and hence doesn't

The bq27000 and bq27010 have a single byte FLAGS register.
Other gauges have 16 bit FLAGS registers.
For reading the FLAGS register it is sufficient to read the single
register instead of reading RSOC at the next higher address as
well and then ignore the high byte.
This does not change functionality but optimizes i2c and hdq

The device's model download function returns the model data as
an array of u32s, which is later compared to the reference
model data. However, since the latter is an array of u16s,
the comparison does not happen correctly, and model verification
fails. This in turn breaks the POR initialization sequence.

Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.
No intended functional changes in this commit.

Commit abf545484d31 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

Pull device mapper fixes from Mike Snitzer:
- a stable dm-flakey fix to error read IO during the 'down_interval'
- a DM core suspend fix to establish the SUSPENDED flag before dropping
the SUSPENDING flag
- a blk-mq request-based DM (dm-mq) dm_stop_queue() fix to properly
stop the blk-mq hw_queues (and cancel pending requeue work); also
set/clear QUEUE_FLAG_STOPPED when stopping/starting the dm-mq
request_queue.
- a DM multipath fix to harden locking of in-core state flags in the
face of concurrent access while handling path failures under heavy
IO.
- a few small DM raid fixes to edge cases caught with further testing.

dm raid: fix processing of max_recovery_rate constructor flag
dm: set DMF_SUSPENDED* _before_ clearing DMF_NOFLUSH_SUSPENDING
dm rq: fix the starting and stopping of blk-mq queues

Pull block fixes from Jens Axboe:
"Here's the second round of block updates for this merge window.
It's a mix of fixes for changes that went in previously in this round,
and fixes in general. This pull request contains:
- Fixes for loop from Christoph
- A bdi vs gendisk lifetime fix from Dan, worth two cookies.
- A blk-mq timeout fix, when on frozen queues. From Gabriel.
- Writeback fix from Jan, ensuring that __writeback_single_inode()
does the right thing.
- Fix for bio->bi_rw usage in f2fs from me.
- Error path deadlock fix in blk-mq sysfs registration from me.
- Floppy O_ACCMODE fix from Jiri.
- Fix to the new bio op methods from Mike.
One more followup will be coming here, ensuring that we don't
propagate the block types outside of block. That, and a rename of
bio->bi_rw is coming right after -rc1 is cut.
- Various little fixes"
* 'for-linus' of git://git.kernel.dk/linux-block:
mm/block: convert rw_page users to bio op use
loop: make do_req_filebacked more robust
loop: don't try to use AIO for discards
blk-mq: fix deadlock in blk_mq_register_disk() error path
Include: blkdev: Removed duplicate 'struct request;' declaration.
Fixup direct bi_rw modifiers
block: fix bdi vs gendisk lifetime mismatch
blk-mq: Allow timeouts to run while queue is freezing
nbd: fix race in ioctl
block: fix use-after-free in seq file
f2fs: drop bio->bi_rw manual assignment
block: add missing group association in bio-cloning functions
blkcg: kill unused field nr_undestroyed_grps
writeback: Write dirty times for WB_SYNC_ALL writeback
floppy: fix open(O_ACCMODE) for ioctl-only open

Pull more ACPI updates from Rafael Wysocki:
"Two more fixes in ACPI drivers, one in the ACPI EC driver
(stable-candidate) and one in the ACPI button driver.
Specifics:
- An ACPI EC driver fix from the 4.3 cycle may cause the ACPICA's
method reentrancy limit to be exceeded for a _Qxx method due to a
large number of concurrent EC operations, so prevent that from
happening by moving the EC handling into a separate workqueue with
a limit on the number of concurrently executed work items (Lv
Zheng)
- Fix the cleanup code in the ACPI button driver that forgets to
clear two variables on exit which causes an error to occur on the
next attmpt to load the driver (Benjamin Tissoires)"

Pull more power management updates from Rafael Wysocki:
"A few more fixes and cleanups in the x86-64 low-level hibernation
code, PM core, cpufreq (Kconfig and intel_pstate), and the operating
points framework.
Specifics:
- Prevent the low-level assembly hibernate code on x86-64 from
referring to __PAGE_OFFSET directly as a symbol which doesn't work
when the kernel identity mapping base is randomized, in which case
__PAGE_OFFSET is a variable (Rafael Wysocki).
- Avoid selecting CPU_FREQ_STAT by default as the statistics are not
required for proper cpufreq operation (Borislav Petkov).
- Add Skylake-X and Broadwell-X IDs to the intel_pstate's list of
processors where out-of-band (OBB) control of P-states is possible
and if that is in use, intel_pstate should not attempt to manage
P-states (Srinivas Pandruvada).
- Drop some unnecessary checks from the wakeup IRQ handling code in
the PM core (Markus Elfring).
- Reduce the number operating performance point (OPP) lookups in one
of the OPP framework's helper functions (Jisheng Zhang)"
* tag 'pm-extra-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
x86/power/64: Do not refer to __PAGE_OFFSET from assembly code
cpufreq: Do not default-yes CPU_FREQ_STAT
cpufreq: intel_pstate: Add more out-of-band IDs
PM / OPP: optimize dev_pm_opp_set_rate() performance a bit
PM-wakeup: Delete unnecessary checks before three function calls
