Pull additional power management updates from Rafael Wysocki:
"These fix an ACPI EC driver bug exposed by the recent rework of the
suspend-to-idle code flow, reintroduce frequency constraints into
device PM QoS (in preparation for adding QoS support to devfreq), drop
a redundant field from struct cpuidle_state and clean up Kconfig in
some places.
Specifics:
- Avoid a race condition in the ACPI EC driver that may cause systems
to be unable to leave suspend-to-idle (Rafael Wysocki)
- Drop the "disabled" field, which is redundant, from struct
cpuidle_state (Rafael Wysocki)
- Reintroduce device PM QoS frequency constraints (temporarily
introduced and than dropped during the 5.4 cycle) in preparation
for adding QoS support to devfreq (Leonard Crestez)
- Clean up indentation (in multiple places) and the cpuidle drivers
help text in Kconfig (Krzysztof Kozlowski, Randy Dunlap)"

This patch adds support for the coulomb counter calibration on init. We do
this by polling for now, and only add partial calibration done interrupt

Then later on when we know for sure we have the calibration done interrupt

interrupt.

Let's allow reconfiguring the cpcap-charger max charge voltage and
default to 4.2V that should be safe for the known users.
This allows the users to use 4.35V for the extra capacity if really
needed at a cost of probably shorter battery life. We check the
constant charge voltage limit set by the battery.
Some pieces of the property setting code is based on an earlier patch
from Pavel Machek <pavel@ucw.cz> but limited to configuring the charge
voltage for now.

With cpcap-charger now using 4.2V instead of 4.35V, we never reach
POWER_SUPPLY_CAPACITY_LEVEL_FULL unless we handle the lowered charge
voltage.
Let's do this by implementing POWER_SUPPLY_PROP_CONSTANT_CHARGE_VOLTAGE,
and assume anything at that level or higher is a full battery.
Let's also make it configurable for users who may still want to
reconfigure it, and notify the charger if supported by the charger.

We can get the low voltage interrupt trigger sometimes way too early,
maybe because of CPU load spikes. This causes orderly_poweroff() be
called too easily.
Let's check the voltage before orderly_poweroff in case it was not
yet a permanent condition. We will be getting more interrupts anyways
if the condition persists.
Let's also show the measured voltages for low battery and battery
empty warnings since we have them.

There have been some cases of droid4 battery bulging that seem to be
related to being left connected to the charger for several weeks.
It is suspected that the 4.35V charge voltage configured for the battery
is too much in the long run, so lets limit the charge voltage to 4.2V.
It could also be that the batteries are just getting old.
We don't really want to just change the charge voltage to 4.2V as Android
may have charged the battery to 4.35V as pointed out by Pavel Machek.
To add checks for battery voltage, the driver needs to understand the
voltage it's charging at, and also needs to better understand it's
charger state. Right now it only understands connect and disconnect,
while now we need to know also a connected state but not charging.
So let's add better charger state handling with help of chrgcurr2 interrupt
for detecting charge full and retry, and add a check for battery voltage
before we start charging. And then we finally can lower the charge voltage
to 4.2V.
Note that we've been using the same register values as the Android distros
on droid4, so it is suspected that the same problem also exists in Android.

We are currently not enabling VBUS boost for cpcap when in host mode.
This means the VBUS is fed at the battery voltage level, which can cause
flakeyness enumerating devices.
Looks like the boost control for VBUS is CPCAP_BIT_VBUS_SWITCH that we
must enable in the charger for nice 4.92 V VBUS output. And looks like
we must not use the STBY pin enabling but must instead use manual VBUS
control in phy-cpcap-usb.
We want to do this in cpcap_charger_vbus_work() and also set a flag for
feeding_vbus to avoid races between USB detection and charger detection,
and disable charging if feeding_vbus is set.

This patch factors out the capacity calibration into one single function
to calibrate the battery capacity, and adding more abnormal cases to
calibrate the capacity when the OCV value is not matchable with current
capacity.
Moreover we also allow to calibrate the capacity when charger magager
tries to get current capacity to make sure we give a correct capacity
for userspace.

We must make sure the alarm capacity is larger than 0, to help to
calibrate the low battery capacity.

The Spreadtrum fuel gauge will multiply by 2 for counting the coulomb
counter to improve the accuracy, which means the value saved in fuel
gauge is: coulomb counter * 2 * 1000ma_adc. Thus fix the conversion
formular to improve the accuracy of calculating the battery capacity.

The variable ret is being assigned with a value that is never
read and it is being updated later with a new value. The
assignment is redundant and can be removed.

devm_add_action_or_reset() is introduced as a helper function which
internally calls devm_add_action(). If devm_add_action() fails
then it will execute the action mentioned and return the error code.
This reduce source code size (avoid writing the action twice)
and reduce the likelyhood of bugs.
