dfcb264a01 power: supply: bq27xxx: Stop and start delayed work in suspend and resume
This driver uses delayed work to perform periodic battery state read out.
This delayed work is not stopped across suspend and resume cycle. The
read out can occur early in the resume cycle. In case of an I2C variant
of this hardware, that read out triggers I2C transfer. That I2C transfer
may happen while the I2C controller is still suspended, which produces a
WARNING in the kernel log.

Fix this by introducing trivial PM ops, which stop the delayed work before
the system enters suspend, and schedule the delayed work right after the
system resumes.

939a116142 power: supply: bq27xxx: Ensure power_supply_changed() is called on current sign changes
On gauges where the current register is signed, there is no charging
flag in the flags register. So only checking flags will not result
in power_supply_changed() getting called when e.g. a charger is plugged
in and the current sign changes from negative (discharging) to
positive (charging).

This causes userspace's notion of the status to lag until userspace
does a poll.

And when a power_supply_leds.c LED trigger is used to indicate charging
status with a LED, this LED will lag until the capacity percentage
changes, which may take many minutes (because the LED trigger only is
updated on power_supply_changed() calls).

Fix this by calling bq27xxx_battery_current_and_status() on gauges with
a signed current register and checking if the status has changed.

c00bc80462 power: supply: bq27xxx: Fix poll_interval handling and races on remove
Before this patch bq27xxx_battery_teardown() was setting poll_interval = 0
to avoid bq27xxx_battery_update() requeuing the delayed_work item.

There are 2 problems with this:

1. If the driver is unbound through sysfs, rather then the module being
   rmmod-ed, this changes poll_interval unexpectedly

2. This is racy, after it being set poll_interval could be changed
   before bq27xxx_battery_update() checks it through
   /sys/module/bq27xxx_battery/parameters/poll_interval

Fix this by added a removed attribute to struct bq27xxx_device_info and
using that instead of setting poll_interval to 0.

There also is another poll_interval related race on remove(), writing
/sys/module/bq27xxx_battery/parameters/poll_interval will requeue
the delayed_work item for all devices on the bq27xxx_battery_devices
list and the device being removed was only removed from that list
after cancelling the delayed_work item.

Fix this by moving the removal from the bq27xxx_battery_devices list
to before cancelling the delayed_work item.

1b27bf793f power: supply: generic-adc-battery: use simple-battery API
Constant battery data is available through power-supply's simple-battery
API. This works automatically, so the manual handling can be removed
without loosing any feature :)

Note, that the POWER_SUPPLY_STATUS_FULL check for the level variable can
be dropped, since the variable is never written. It can be re-introduced
properly once the driver gets functionality to calculate the current
charge level. Apart from that the check must be done fuzzy anyways,
since charge estimation usually is not precise enough to always return
exactly the full charge capacity for a full battery.

ed4520d6a1 soc: ti: Remove pm_runtime_irq_safe() usage for smartreflex
For the smartreflex device, we need to disable smartreflex on SoC idle,
and have been using pm_runtime_irq_safe() to do that. But we want to
remove the irq_safe usage as PM runtime takes a permanent usage count
on the parent device with it.

In order to remove the need for pm_runtime_irq_safe(), let's gate
the clock directly in the driver. This removes the need to call PM runtime
during idle, and allows us to switch to using CPU_PM in the following
patch.

Note that the smartreflex interconnect target module is configured for smart
idle, but the clock does not have autoidle capability, and needs to be gated
manually. If the clock supported autoidle, we would not need to even gate
the clock.

With this change, we can now remove the related quirk flags for ti-sysc
also.

4eed7f5a83 power: supply: bq27xxx: Add support for BQ78Z100
Add support for TI BQ78Z100, I2C interface gas gauge.
It provides a fully integrated safety protection
and authentication for 1 to 2-series cell Li-Ion and
Li-Polymer battery packs.

The patch was tested with BQ78Z100 equipment.

	POWER_SUPPLY_TEMP=269
	POWER_SUPPLY_TIME_TO_EMPTY_NOW=1249920
	POWER_SUPPLY_TECHNOLOGY=Li-ion
	POWER_SUPPLY_CHARGE_FULL=6494000
	POWER_SUPPLY_CHARGE_NOW=1736000
	POWER_SUPPLY_CHARGE_FULL_DESIGN=6000000
	POWER_SUPPLY_CYCLE_COUNT=1
	POWER_SUPPLY_POWER_AVG=-20000
	POWER_SUPPLY_HEALTH=Good
	POWER_SUPPLY_MANUFACTURER=Texas Instruments

CASE II : No discharging current:
	POWER_SUPPLY_NAME=bq78z100-0
	POWER_SUPPLY_STATUS=Not charging
	POWER_SUPPLY_PRESENT=1
	POWER_SUPPLY_VOLTAGE_NOW=3386000
	POWER_SUPPLY_CURRENT_NOW=0

c4d57c22ac power: supply: bq27xxx: fix power_avg for newer ICs
On all newer bq27xxx ICs, the AveragePower register contains a signed
value; in addition to handling the raw value as unsigned, the driver
code also didn't convert it to µW as expected.

At least for the BQ28Z610, the reference manual incorrectly states that
the value is in units of 1mW and not 10mW. I have no way of knowing
whether the manuals of other supported ICs contain the same error, or if
there are models that actually use 1mW. At least, the new code shouldn't
be *less* correct than the old version for any device.

power_avg is removed from the cache structure, se we don't have to
extend it to store both a signed value and an error code. Always getting
an up-to-date value may be desirable anyways, as it avoids inconsistent
current and power readings when switching between charging and
discharging.

c1f73028f7 power: supply: charger-manager: Update extcon functions
In commit 830ae44220 ("extcon: Remove the deprecated extcon functions")
the function extcon_register_interest became a no-op returning an error,
leading to non-functional behaviour in charger-manager.

Additionally, a translation table is needed between the text representation
of the extcon cable names and their IDs is needed.  In order to retain DT
compatibility, TA and CHARGE-DOWNSTREAM are added as they were present up
until commit 11eecf910b ("extcon: Modify the id and name of external
connector")

e132fc6bb8 power: supply: charger-manager: Make decisions focussed on battery status
cm_monitor(), where charging management starts, checks various charging
condition sequentially to decide next charging operation. However, as it
follows sequential process, cascaded if statements, it does some
jobs which have already done in the previous stage. This results in a
delay in decision making. Moreover, starting point of charging is spread
all around which makes maintain code and debugging difficult.

Both of the problems mentioned above become clean if it manages battery
charging focusing on battery status not following sequential condition
checking.  Now, cm_monitor() moves battery state diagram and does the
optimal operation for current state. As a result, it reduces whole
monitoring time almost in half.
