Currently the bigjoiner state copy logic is kind of
a byzantine mess.
Clean it up to operate in the following manner during a full
modeset:
1) master uapi -> hw state copy
2) master hw -> slave hw state copy
And during a non-modeset update we do:
1) master uapi -> hw state light copy
2) master hw -> slave hw state light copy
I think that is now easier to reason about since we never do
any kind of master uapi -> slave hw state copy short circuit
that could happen previously.
Obviously this does now depend on the master uapi->hw copy
always happening before the master hw -> slave hw copy, but
that is guaranteed by the fact that we always add both crtcs
to the state early, the crtcs are registered in pipe
order (so the compute_config loop happens in pipe order),
and the hardware requires the master pipe has to be lower
than the slave pipe as well. And for good measure we shall
add a check+WARN for this before doing the bigjoiner crtc
assignment.

There's some weird junk in intel_atomic_check_bigjoiner()
that's trying to look at the old crtc state's bigjoiner
usage for some reason. That code is totally unnecessary,
and maybe even actively harmful. Not entirely sure which
since it's such a mess that I can't actually wrap my brain
around what it ends up doing.
Either way, thanks to intel_bigjoiner_add_affected_crtcs()
all of the old bigjoiner crtcs are guaranteed to be in the
state already if any one of them is in the state. Also if
any one of those crtcs got flagged for a modeset, then all
of them will have been flagged, and the bigjoiner links
will have been detached via kill_bigjoiner_slave().
So there is no need to look examing any old bigjoiner
usage in intel_atomic_check_bigjoiner(). All we have to care
about is whether bigjoiner is needed for the new state,
and whether we can get the slave crtc we need.

We seem to be missing a few things from the bigjoiner state copy.
Namely hw.mode isn't getting copied (which probably causes PIPESRC
to be misconfigured), CTM/LUTs aren't getting copied (which could
cause the pipe to produced incorrect output), and we also forgot
to copy over the color_mgmt_changed flag so potentially we fail
to do the actual CTM/LUT programming (assuming we aren't doing
a full modeset or fastset). Fix it all.

The core doesn't flag scaling_filter prop changes as needing
a modeset. That doesn't work for us since we only reprogram the
pipe scaler during full modesets and fastsets. So we need to
flag the prop change as a modeset ourselves. Assuming nothing else
has changed the operation will get promoted (demoted?) to a fastset
later.

This reverts commit 0e8ae5a6ff5952253cd7cc0260df838ab4c21009.
0e8ae5a6ff59 ("PCI/portdrv: Do not setup up IRQs if there are no users")
reduced usage of IRQs when we don't think we need them. But Joey, Sergiu,
and David reported choppy GUI rendering, systems that became unresponsive
every few seconds, incorrect values reported by cpufreq, and high IRQ 16
CPU usage.
Joey bisected the issues to 0e8ae5a6ff59, so revert it until we figure out
a better solution.

When using USB charging, the AB8500 charger is periodically
checking VBAT for a threshold at 3.8V.
This crashes badly, as the class_for_each_device() was passed
the wrong argument. I think this has maybe worked by chance
in the past because of how the structs were arranged but it
is leading to crashes now.
Fix this up and also switch to using microvolts for the
voltages like the rest of the code.

The BATCTRL mode reads the temperature of the battery by
enabling a certain probing current (7-20 mA) and then measure
the voltage of the NTC mounted inside the battery.
None of the AB8500 product or the reference designs use this
mode. What we use is the so-called BATTEMP mode which enables
an internal 230 kOhm pull-up to 1.8 V to the external NTC on
pin BatTemp (N16) and then measures the voltage over the NTC
using the ADC:
1.8V (VTVOUT)

[ ] 230 kOhm

BatTemp +---------------- ADC
Pin N16 | _
|/
[/] NTC

Cut out the BATCTRL code to clear the forest and stop
maintaining code we can never test.
The current inducing method is still used to probe for the
battery type using the internal BTI (battery type indicator)
on the BatCtrl (C3) pin in a separate code path.

Add a new battery driver for the uPI uG3105 battery monitor.
Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead it
is expected to be use in combination with some always on microcontroller
reading its coulomb-counter before it can wrap (must be read every 400
seconds!).
Since Linux does not monitor coulomb-counter changes while the device is
off or suspended, the coulomb counter is not used atm.
So far this driver is only used on x86/ACPI (non devicetree) devs
(also note there is no of_match table). Therefor there is no devicetree
bindings documentation for this driver's "upisemi,rsns-microohm" property
since this is not used in actual devicetree files and the dt bindings
maintainers have requested properties with no actual dt users to
_not_ be added to the dt bindings.
The property's name has been chosen so that it should not need to be
changed if/when devicetree enumeration support gets added later, as it
mirrors "maxim,rsns-microohm" from the "maxim,max17042" bindings.

If the fwnode data as parsed by power_supply_get_battery_info() provides
max values for ccc_ireg and cvc_vreg then do not allow the user to later
set these to higher values then those specified by the firmware,
otherwise the battery might get damaged.

So far the bq24190_charger driver has been relying on either the chips
default constant_charge_current_max_ua and constant_charge_voltage_max_uv
values, or on the BIOS or bootloader to program these for us.
This does not happen on all boards, causing e.g. the wrong (too low)
values to be used on Lenovo Yoga Tablet 2 830F/L and 1050F/L tablets.
If power_supply_get_battery_info() provides us with values for these
settings, then program the charger accordingly.
And if the user later overrides these values then save the user-values
so that these will be restored after a suspend/resume.

Store ichg-max and vreg-max in bq24190_dev_info once from
bq24190_get_config() and drop the bq24190_charger_get_current_max() and
bq24190_charger_get_voltage_max() helpers.
This is a preparation patch for honoring the
constant_charge_current_max_ua and constant_charge_voltage_max_uv
values from power_supply_get_battery_info().

power_supply_get_battery_info() now also supports getting battery_info
on boards not using dt/of. Remove the of_node check. If neither of nor
other battery-info is present the function will fail making this change
a no-op in that case.
