Here is the large set of USB and Thunderbolt driver changes for 6.2-rc1.
Overall, thanks to the removal of a driver, more lines were removed than
added, a nice change. Highlights include:
- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many USB
and other subsystem drivers, that ended up breaking the build. That
will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates
All of these have been in linux-next for a while with no reported
problems.

Quite a quiet release for regulator, the diffstat is dominated by the
I2C migration to probe_new() and the newly added MT6357 driver. We've
just one framework addition and the rest is all new device support,
fixes and cleanups.
The framework addition is an API for requesting all regulators defined
in DT, this isn't great practice but has reasonable applications when
there is generic code handling devices on buses where the bus
specification doesn't include power. The immediate application is MDIO
but I believe there's others, it's another API that'll need an eye
keeping on it for undesirable usage.
- An API for requesting all regulators defined in DT.
- Conversion of lots of drivers to the I2C probe_new() API.
- Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and

There's a cross tree merge with the I2C tree in order to use the new
i2c_client_get_device_id() helper in the conversions to probe_new().

Merge ACPI changes related to device enumeration, device object
managenet, operation region handling, table parsing and sysfs
interface:
- Use ZERO_PAGE(0) instead of empty_zero_page in the ACPI device
enumeration code (Giulio Benetti).
- Change the return type of the ACPI driver remove callback to void and
update its users accordingly (Dawei Li).
- Add general support for FFH address space type and implement the low-
level part of it for ARM64 (Sudeep Holla).
- Fix stale comments in the ACPI tables parsing code and make it print
more messages related to MADT (Hanjun Guo, Huacai Chen).
- Replace invocations of generic library functions with more kernel-
specific counterparts in the ACPI sysfs interface (Christophe JAILLET,
Xu Panda).
* acpi-scan:
ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0)
* acpi-bus:
ACPI: FFH: Silence missing prototype warnings
ACPI: make remove callback of ACPI driver void
ACPI: bus: Fix the _OSC capability check for FFH OpRegion
arm64: Add architecture specific ACPI FFH Opregion callbacks
ACPI: Implement a generic FFH Opregion handler
* acpi-tables:
ACPI: tables: Fix the stale comments for acpi_locate_initial_tables()
ACPI: tables: Print CORE_PIC information when MADT is parsed
* acpi-sysfs:
ACPI: sysfs: use sysfs_emit() to instead of scnprintf()
ACPI: sysfs: Use kstrtobool() instead of strtobool()
Had a duplicate event typo, so just fixed the 1 character typo.

The Lenovo Yoga Tab 3 (YT3-X90F) is an Intel Cherry Trail based tablet
which ships with Android as Factory OS. Its DSDT contains a bunch of I2C
devices which are not actually there, causing various resource conflicts.
Use acpi_quirk_skip_i2c_client_enumeration() to not enumerate these.
The YT3-X90F has quite a bit of exotic hardware, this adds initial
support by manually instantiating the i2c-clients for the 2 charger +
2 fuel-gauge chips used for the 2 batteries.
Support for other parts of the hw will be added by follow-up patches.

Following by the below discussion, there's the potential UAF issue
between regulator and mfd.
https://lore.kernel.org/all/20221128143601.1698148-1-yangyingliang@huawei.com/
From the analysis of Yingliang
CPU A |CPU B
mt6370_probe() |
devm_mfd_add_devices() |
|mt6370_regulator_probe()
| regulator_register()
| //allocate init_data and add it to devres
| regulator_of_get_init_data()
i2c_unregister_device() |
device_del() |
devres_release_all() |
// init_data is freed |
release_nodes() |
| // using init_data causes UAF
| regulator_register()
It's common to use mfd core to create child device for the regulator.
In order to do the DT lookup for init data, the child that registered
the regulator would pass its parent as the parameter. And this causes
init data resource allocated to its parent, not itself. The issue happen
when parent device is going to release and regulator core is still doing
some operation of init data constraint for the regulator of child device.
To fix it, this patch expand 'regulator_register' API to use the
different devices for init data allocation and DT lookup.

For bus-based driver, device removal is implemented as:
1 device_remove()->
2 bus->remove()->
3 driver->remove()
Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d5
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.
Now we have the situation that both 1 & 2 of calling chain are
void-returned, so it does not make much sense for 3(driver->remove)
to return non-void to its caller.
So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.
This change, for itself, is for device drivers based on acpi-bus.

Remove the ACPI-HID + DMI-id deny-lists for touchpad_ctrl_via_ec and
instead make it a module option which defaults to false.
The touchpad sysfs attribute allowing directly writing VPCCMD_W_TOUCHPAD
from userspace has been leading to a lot of bug-reports / patches adding
both ACPI HID + dmi-id based deny-lists for it which then need to be
expanded all the time going forward leading to a high maintenance load.
At the same time the touchpad sysfs attribute is not a standard Linux
userspace API. So it is not used in standard desktop-enviroments, instead
it is only used in the following 2 rare circumstances:
1. Ideapad specific control-panel like applets
2. Custom scripts written by users
For 1. these applets need to already deal with the touchpad sysfs attr
sometimes not being there because of the existing deny lists so hiding
it be default should not cause an issue; and most desktop environments
already have a touchpad-disable option in their native control-panel,
so having an ideapad specific toggle for this is not necessary.
For 2. since these users are already customizing their systems they
can add the module option if they want to keep using the touchpad
sysfs attribute.

Commit d69cd7eea9 ("platform/x86: ideapad-laptop: Disable touchpad_switch
for ELAN0634") from Janary 2021 added a flag hiding the touchpad sysfs-attr
and disabling ideapad_sync_touchpad_state() because some devices
"do not use EC to switch touchpad".
At the same time this added a write(VPCCMD_W_TOUCHPAD, 1) call at probe
time on these same devices. This seems to be copied from the rfkill code
which does something similar when hw rfkill support is disabled.
But for the rfkill code this is known to be necessary on some models,
where as for the touchpad control no motivation is given for doing this
and prior to this patch there were no reports of needing to do this.
So this seems unnecessary; and it is best to avoid poking the hardware
unnecessary to avoid unwanted side effects, so remove this.

On recent Ideapad models the EC does not control the touchpad at all,
so instead of sending KEY_TOUCHPAD_ON/ _OFF on touchpad toggle hotkey
events, ideapad-laptop should send KEY_TOUCHPAD_TOGGLE and let userspace
handle the toggling.
Check for this by checking if the value read from VPCCMD_R_TOUCHPAD
actually changes when receiving a touchpad-toggle hotkey event; and
if it does not change send KEY_TOUCHPAD_TOGGLE to userspace to let
userspace enable/disable the touchpad in software.
Note this also drops the priv->features.touchpad_ctrl_via_ec check from
ideapad_sync_touchpad_state() so that KEY_TOUCHPAD_TOGGLE will be send
on laptops where this is not set too. This can be safely dropped now
because the i8042_command(I8042_CMD_AUX_ENABLE/_DISABLE) call is now
guarded by its own feature flag.

Recently there have been multiple patches to disable the ideapad-laptop's
touchpad control code, because it is causing issues on various laptops:
Commit d69cd7eea9 ("platform/x86: ideapad-laptop: Disable touchpad_switch for ELAN0634")
Commit a231224a60 ("platform/x86: ideapad-laptop: Disable touchpad_switch")
The turning on/off of the ps2 aux port was added specifically for
the IdeaPad Z570, where the EC does toggle the touchpad on/off LED and
toggles the value returned by reading VPCCMD_R_TOUCHPAD, but it does not
actually turn on/off the touchpad.
The ideapad-laptop code really should not be messing with the i8042
controller on all devices just for this special case.
Add a new ctrl_ps2_aux_port flag set based on a DMI based allow-list
for devices which need this workaround, populating it with just
the Ideapad Z570 for now.
This also adds a module parameter so that this behavior can easily
be enabled on other models which may need it.

Initial implementation assumed a single IFS test image file with a
fixed name ff-mm-ss.scan. (where ff, mm, ss refers to family, model and
stepping of the core).
Subsequently, it became evident that supporting more than one test
image file is needed to provide more comprehensive test coverage. (Test
coverage in this scenario refers to testing more transistors in the core
to identify faults).
The other alternative of increasing the size of a single scan test image
file would not work as the upper bound is limited by the size of memory
area reserved by BIOS for loading IFS test image.
Introduce "current_batch" file which accepts a number. Writing a
number to the current_batch file would load the test image file by
name ff-mm-ss-<xy>.scan, where <xy> is the number written to the
"current_batch" file in hex. Range check of the input is done to verify
it not greater than 0xff.
For e.g if the scan test image comprises of 6 files, they would be named:
06-8f-06-01.scan
06-8f-06-02.scan
06-8f-06-03.scan
06-8f-06-04.scan
06-8f-06-05.scan
06-8f-06-06.scan
And writing 3 to current_batch would result in loading 06-8f-06-03.scan
above. The file can also be read to know the currently loaded file.
And testing a system looks like:
for each scan file
do
load the IFS test image file (write to the batch file)
for each core
do
test the core with this set of tests
done
done
Qualify few error messages with the test image file suffix to provide
better context.
