Right now, is impossible for battery hook callbacks
to access instance-specific data, forcing most drivers
to provide some sort of global state. This however is
difficult for drivers which can be instantiated multiple
times and/or are hotplug-capable.
Pass a pointer to the battery hook to those callbacks
for usage with container_of().

Commit 3ae86d2d47 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock
LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops
to manually toggle the fn-lock LED because the EC does not do it itself.
However, the same WMI ID is also sent on some Yoga laptops. Here, setting
the fn-lock state is not valid behavior, and causes the EC to spam
interrupts until the laptop is rebooted.
Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to
manually set the LED on models on this list.

Add device nodes to enable support for battery and charger status, the

(including sensors, touchpad, keyboard, and other miscellaneous devices)
on the Surface Pro 9.
This does not include support for a tablet-mode switch yet, as that is
now handled via the POS subsystem (unlike the Surface Pro 8, where it is
handled via the KIP subsystem) and therefore needs further changes.
While we're at it, also add the missing comment for the Surface Pro 8.

Currently, we check any received packet whether we have already seen it
previously, regardless of the packet type (sequenced / unsequenced). We
do this by checking the sequence number. This assumes that sequence
numbers are valid for both sequenced and unsequenced packets. However,
this assumption appears to be incorrect.
On some devices, the sequence number field of unsequenced packets (in
particular HID input events on the Surface Pro 9) is always zero. As a
result, the current retransmission check kicks in and discards all but
the first unsequenced packet, breaking (among other things) keyboard and
touchpad input.
Note that we have, so far, only seen packets being retransmitted in
sequenced communication. In particular, this happens when there is an
ACK timeout, causing the EC (or us) to re-send the packet waiting for an
ACK. Arguably, retransmission / duplication of unsequenced packets
should not be an issue as there is no logical condition (such as an ACK
timeout) to determine when a packet should be sent again.
Therefore, remove the retransmission check for unsequenced packets
entirely to resolve the issue.

The current logic in the Intel PMC driver will forcefully attach it
when detecting any CPU on the intel_pmc_core_platform_ids array,
even if the matching ACPI device is not present.
There's no checking in pmc_core_probe() to assert that the PMC device
is present, and hence on virtualized environments the PMC device
probes successfully, even if the underlying registers are not present.
Before commit 21ae435709 ("platform/x86: intel_pmc_core: Substitute PCI
with CPUID enumeration") the driver would check for the presence of a
specific PCI device, and that prevented the driver from attaching when
running virtualized.
Fix by only forcefully attaching the PMC device when not running
virtualized. Note that virtualized platforms can still get the device
to load if the appropriate ACPI device is present on the tables
provided to the VM.
Make an exception for the Xen initial domain, which does have full
hardware access, and hence can attach to the PMC if present.

Wifi is soft blocked by checking rfkill. When unblocked manually,
after few seconds it would be soft blocked again. So I was suspecting
something triggered rfkill to soft block wifi. At the end it was
fixed by removing hp_wmi module.
The root cause is the way hp-wmi driver handles command 1B on
post-2009 BIOS. In pre-2009 BIOS, command 1Bh return 0x4 to indicate
that BIOS no longer controls the power for the wireless devices.

The for_each_acpi_consumer_dev() takes a reference to the iterator
and if we break a loop we must drop that reference. This usually
happens when error handling is involved. However it's not the case
for skl_int3472_fill_clk_pdata().
Don't leak reference on error by dropping it properly.

The idle mask is dumped during the "prepare" and "restore" stage
right now, which helps to demonstrate issues only related to the
first s2idle entry.
If the system has entered s2idle once, but was woken up never
breaking the s2idle loop but also never went back to sleep we
might still have another issue to deal with however.
Move the dynamic debugging message here so that we'll catch it on
each iteration.

It is observed that when thinkpad_acpi driver loads before amd-pmf
driver, thinkpad_acpi driver sends the AMT "on" event and the request
immediately will be part of the PMF BIOS "pending requests".
With the current amd-pmf code, as soon as the amd-pmf driver gets
probed, it calls apmf_acpi_init() where the notify handler will be
installed. Handler callback would call amd_pmf_handle_amt() where the
amd_pmf_set_automode() shall update the auto-mode thermals.
In this case, the auto-mode config_store shall have "zeros", as the
auto mode init gets called during the later stage.
To fix this, change the order of the acpi notifer install and call it
after the auto mode initialization is done.

Currently, we only support passing a single gpiod_lookup_table as part
of the board data for the tps68470 driver. This carries the implicit
assumption that each TPS68470 device will only support a single
sensor, which does not hold true.
Extend the code to support the possibility of multiple sensors each
having a gpiod_lookup_table, and opportunistically add the lookup
table for the Surface Go line's IR camera.

At present, the tps68470.c only supports a single clock consumer when
passing platform data to the clock driver. In some devices multiple
sensors depend on the clock provided by a single TPS68470 and so all
need to be able to acquire the clock. Support passing multiple
consumers as platform data.

In commit b83e2b3067 ("ACPI: scan: Add function to fetch dependent
of ACPI device") we added a means of fetching the first device to
declare itself dependent on another ACPI device in the _DEP method.
One assumption in that patch was that there would only be a single
consuming device, but this has not held.
Replace that function with a new function that fetches the next consumer
of a supplier device. Where no "previous" consumer is passed in, it
behaves identically to the original function.

Whether to turn CnQF on/off by default upon driver load would be decided
by a BIOS flag. Add a sysfs node to provide a way to the user whether to
use static slider or CnQF .

CnQF (a.k.a Cool and Quiet Framework) extends the static slider concept.
PMF dynamically manages system power limits and fan policy based on system
power trends which is representative of workload trend.
Static slider and CnQF controls are mutually exclusive for system power
budget adjustments. CnQF supports configurable number of modes which can
be unique for AC and DC. Every mode is representative of a system state
characterized by unique steady state and boost behavior.
OEMs can configure the different modes/system states and how the
transition to a mode happens. Whether to have CnQF manage system power
budget dynamically in AC or DC or both is also configurable. Mode changes
due to CnQF don't result in slider position change.
The default OEM values are obtained after evaluating the PMF ACPI function
idx 11 & 12 for AC and DC respectively. Whether to turn ON/OFF by default
is guided by a "flag" passed by the OEM BIOS.
