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 "fg_wq" is used for running the FG algorithm periodically.
It has been identity converted.
It has multiple work items viz fg_periodic_work, fg_low_bat_work,

which require execution ordering. Hence, a dedicated ordered workqueue
has been used here.

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

The workqueue "charger_wq" is used for the IRQs and checking HW state of
the charger. It has been identity converted.
It has multiple work items viz usb_charger_attached_work, kick_wd_work,
check_vbat_work, check_hw_failure_work, usb_charger_attached_work,
ac_work, ac_charger_attached_work, attach_work and check_usbchgnotok_work,
which require execution ordering. Hence, a dedicated ordered workqueue
has been used here.
The WQ_MEM_RECLAIM flag has also been set to ensure
forward progress under memory pressure.

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
require ordering. Hence, alloc_workqueue has been used to replace the
deprecated create_singlethread_workqueue instance.
Since PMIC battery status needs to be monitored for any change, the
WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory
pressure.
Since there is a single work item, explicit concurrency
limit is unnecessary here.

alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces

The workqueue "charger_wq" is used for running all the charger related
tasks. This involves charger detection, checking for HW failure and HW
status. This workqueue has been identity converted.
It queues multiple workitems viz &pm2->check_main_thermal_prot_work,
&pm2->check_hw_failure_work, &pm2->ac_work. Hence, the deprecated
create_singlethread_workqueue() instance has been replaced with a

Battery capacity level is a standard feature of sbs battery
That can be used to tell what the remainig battery capacity is, and
can tell if the battery has not been calibrated/initialized, which makes
the capacity and charging/discharging percentages invalid.

Currently the battery detect gpio can not be used with a chained interrupt
controller that requires threaded irq handlers. Use threaded irq instead.
In addition this was not going to be working at present because
chip->power_supply is assigned after the request irq call.

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
traffic.

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
