[ Upstream commit 6e9b8992b1 ]
The purpose of this patch is to provide a central location where all
HP related drivers are found. HP drivers will recide under
drivers/platform/x86/hp directory.
Introduce changes to Kconfig file to list all HP driver under "HP X86
Platform Specific Device Drivers" menu option. Additional changes
include update MAINTAINERS file to indicate hp related drivers new
path.

[ Upstream commit 2f0cf1e85d ]
The Acer Iconia One 7 B1-750 is a x86 ACPI tablet which ships with Android
x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there, causing various resource conflicts. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().
Add support for manually instantiating the I2C + other devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.

commit 1684878952 upstream.
There has been a lot of confusion around which platform profiles are
supported on various platforms and it would be useful to have a debug
method to be able to override the profile mode that is selected.
I don't expect this to be used in anything other than debugging in
conjunction with Lenovo engineers - but it does give a way to get a
system working whilst we wait for either FW fixes, or a driver fix
to land upstream, if something is wonky in the mode detection logic

commit 0c0cd3e25a upstream.
I had incorrectly thought that PSC profiles were not usable on Intel
platforms so had blocked them in the driver initialistion. This broke
platform profiles on the T490.
After discussion with the FW team PSC does work on Intel platforms and
should be allowed.
Note - it's possible this may impact other platforms where it is advertised
but special driver support that only Windows has is needed. But if it does
then they will need fixing via quirks. Please report any issues to me so I
can get them addressed - but I haven't found any problems in testing...yet

The current SMN index used for the driver probe seems to be meant
for the BIOS pair and there are potential concurrency problems that can
occur with an inopportune SMI.
It is been advised to use SMN_INDEX_0 instead of SMN_INDEX_2, which is
what amd_nb.c provides and this function has protections to ensure that
only one caller can use it at a time.

commit e3271a5917 upstream.
Commit 5829f8a897 ("platform/x86: ideapad-laptop: Send
KEY_TOUCHPAD_TOGGLE on some models") made ideapad-laptop send
KEY_TOUCHPAD_TOGGLE when we receive an ACPI notify with VPC event bit 5 set
and the touchpad-state has not been changed by the EC itself already.
This was done under the assumption that this would be good to do to make
the touchpad-toggle hotkey work on newer models where the EC does not
toggle the touchpad on/off itself (because it is not routed through
the PS/2 controller, but uses I2C).
But it turns out that at least some models, e.g. the Yoga 7-15ITL5 the EC
triggers an ACPI notify with VPC event bit 5 set on resume, which would
now cause a spurious KEY_TOUCHPAD_TOGGLE on resume to which the desktop
environment responds by disabling the touchpad in software, breaking
the touchpad (until manually re-enabled) on resume.
It was never confirmed that sending KEY_TOUCHPAD_TOGGLE actually improves
things on new models and at least some new models like the Yoga 7-15ITL5
don't have a touchpad on/off toggle hotkey at all, while still sending
ACPI notify events with VPC event bit 5 set.
So it seems best to revert the change to send KEY_TOUCHPAD_TOGGLE when
receiving an ACPI notify events with VPC event bit 5 and the touchpad
state as reported by the EC has not changed.
Note this is not a full revert the code to cache the last EC touchpad
state is kept to avoid sending spurious KEY_TOUCHPAD_ON / _OFF events
on resume.

[ Upstream commit fb5755100a ]
For platforms with Alder Lake PCH (Alder Lake S and Raptor Lake S) the
slp_s0_residency attribute has been reporting the wrong value. Unlike other
platforms, ADL PCH does not have a counter for the time that the SLP_S0
signal was asserted. Instead, firmware uses the aggregate of the Low Power
Mode (LPM) substate counters as the S0ix value. Since the LPM counters run
at a different frequency, this lead to misreporting of the S0ix time.
Add a check for Alder Lake PCH and adjust the frequency accordingly when
display slp_s0_residency.

[ Upstream commit 03f5eb300a ]
REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on REGMAP" to "select REGMAP".
For NVSW_SN2201, select REGMAP_I2C instead of depending on it.

commit 0d9bdd8a55 upstream.
On some Lenovo Legion models, the backlight might be driven by either
one of nvidia_wmi_ec_backlight or amdgpu_bl0 at different times.
When the Nvidia WMI EC backlight interface reports the backlight is
controlled by the EC, the current backlight handling only registers
nvidia_wmi_ec_backlight (and registers no other backlight interfaces).
This hides (never registers) the amdgpu_bl0 interface, where as prior
to 6.1.4 users would have both nvidia_wmi_ec_backlight and amdgpu_bl0
and could work around things in userspace.
Add a force module parameter which can be used with acpi_backlight=native
to restore the old behavior as a workound (for now) by passing:
"acpi_backlight=native nvidia-wmi-ec-backlight.force=1"

[ Upstream commit 8e60615e89 ]
By default when the system is configured for low power idle in the FADT
the keyboard is set up as a wake source. This matches the behavior that
Windows uses for Modern Standby as well.
It has been reported that a variety of AMD based designs there are
spurious wakeups are happening where two IRQ sources are active.
For example:
```
PM: Triggering wakeup from IRQ 9
PM: Triggering wakeup from IRQ 1
```
In these designs IRQ 9 is the ACPI SCI and IRQ 1 is the keyboard.
One way to trigger this problem is to suspend the laptop and then unplug
the AC adapter. The SOC will be in a hardware sleep state and plugging
in the AC adapter returns control to the kernel's s2idle loop.
Normally if just IRQ 9 was active the s2idle loop would advance any EC
transactions and no other IRQ being active would cause the s2idle loop
to put the SOC back into hardware sleep state.
When this bug occurred IRQ 1 is also active even if no keyboard activity
occurred. This causes the s2idle loop to break and the system to wake.
This is a platform firmware bug triggering IRQ1 without keyboard activity.
This occurs in Windows as well, but Windows will enter "SW DRIPS" and
then with no activity enters back into "HW DRIPS" (hardware sleep state).
This issue affects Renoir, Lucienne, Cezanne, and Barcelo platforms. It
does not happen on newer systems such as Mendocino or Rembrandt.
It's been fixed in newer platform firmware. To avoid triggering the bug
on older systems check the SMU F/W version and adjust the policy at suspend
time for s2idle wakeup from keyboard on these systems. A lot of thought
and experimentation has been given around the timing of disabling IRQ1,
and to make it work the "suspend" PM callback is restored.
