Wenyou Yang a09209acd6 power: supply: act8945a_charger: Add status change update support
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.

Wenyou Yang 1f0ba4067a power: supply: act8945a_charger: Improve state handling
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.

Wenyou Yang 6b021fc910 power: supply: act8945a_charger: Remove "battery_temperature"
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.

Wenyou Yang 5da643b26d power: supply: act8945a_charger: Achieve properties from its node
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.

Paul Kocialkowski ae0f74be6e power: bq24735-charger: Assume not charging when charger is missing
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.

Bhaktipriya Shridhar b732ace40a power: ds2760_battery: Remove deprecated create_singlethread_workqueue
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.

Bhaktipriya Shridhar 829f0e97cc power: ipaq_micro_battery: Remove deprecated create_singlethread_workqueue
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.

It queues a single work item (pbi->monitor_battery) and hence doesn't

H. Nikolaus Schaller e4a404a081 power:bq27xxx: 27000/10 read FLAGS register as single
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.
