"Core code:
- Provide a generic wrapper which can be utilized in drivers to
handle the problem of force threaded demultiplex interrupts on RT
enabled kernels. This avoids conditionals and horrible quirks in
drivers all over the place
- Fix up affected pinctrl and GPIO drivers to make them cleanly RT
safe
Interrupt drivers:
- A new driver for the FSL MU platform specific MSI implementation
- Make irqchip_init() available for pure ACPI based systems
- Provide a functional DT binding for the Realtek RTL interrupt chip
- The usual DT updates and small code improvements all over the

ACPI thermal driver, add ACPI support for non-GPE system wakeup events
and make the system reboot code use the S5 (system off) state by

Specifics:
- Fix ACPI device object reference counting in (recently updated)

- Fix a memory leak in APEI by avoiding to add a task_work to kernel
threads running when an asynchronous error is detected (Shuai Xue).
- Add ACPI support for handling system wakeups via GPIO wake capable
IRQs in addition to GPEs (Raul E Rangel).
- Make the system reboot code put ACPI-enabled systems into the S5

expected (Kai-Heng Feng).

consistent and drop redundant code from it (Rafael Wysocki)"

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.

- Rearrange ACPI device object initialization code (Rafael Wysocki).
- Drop parent field from struct acpi_device (Rafael Wysocki).

of a single TPS68470 along with the requisite framework-level
support (Daniel Scally).

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.

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.
