Pull drm updates from Dave Airlie:
"This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices,
it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more
upstream focused development model, and trying to maximise code
sharing. It's not enabled for any hw by default, and will hopefully
get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long
enough.
amdgpu has a bunch of new color management code that is being used in
the Steam Deck.
amdgpu also has a new ACPI WBRF interaction to help avoid radio
interference.

It was reported [0] that adding a generic joycon to the system caused
a kernel crash on Steam Deck, with the below panic spew:
divide error: 0000 [#1] PREEMPT SMP NOPTI
[...]
Hardware name: Valve Jupiter/Jupiter, BIOS F7A0119 10/24/2023
RIP: 0010:nintendo_hid_event+0x340/0xcc1 [hid_nintendo]

Since it's a divide-by-0 error, by tracking the code for potential
denominator issues, we've spotted 2 places in which this could happen;
so let's guard against the possibility and log in the kernel if the
condition happens. This is specially useful since some data that
fills some denominators are read from the joycon HW in some cases,
increasing the potential for flaws.

Commit 46a0a2c96f0f ("HID: lenovo: Detect quirk-free fw on cptkbd and
stop applying workaround") introduced a regression for ThinkPad
TrackPoint Keyboard II which has similar quirks to cptkbd (so it uses
the same workarounds) but slightly different so that there are
false-positives during detecting well-behaving firmware. This commit
restricts detecting well-behaving firmware to the only model which
known to have one and have stable enough quirks to not cause
false-positives.

Users have reported problems with recent Lenovo laptops that contain
an IDEA5002 I2C HID device. Reports include fans turning on and
running even at idle and spurious wakeups from suspend.
Presumably in the Windows ecosystem there is an application that
uses the HID device. Maybe that puts it into a lower power state so
it doesn't cause spurious events.
This device doesn't serve any functional purpose in Linux as nothing
interacts with it so blacklist it from being probed. This will
prevent the GPIO driver from setting up the GPIO and the spurious
interrupts and wake events will not occur.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.
Furthermore, let's make sure `hid->xyz` and `ev->u.create2.xyz` are the
same size at compile time to prevent silent truncation.
With these changes, it is abundantly clear what the intent and behavior
of the code is -- We are getting a string to string copy with
NUL-termination and no truncation.

Honor MagicBook 13 2023 has a touchpad which do not switch to the multitouch
mode until the input mode feature is written by the host. The touchpad do
report the input mode at touchpad(3), while itself working under mouse mode. As
a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set
feature in mt_set_input_mode for such device.
The touchpad reports as BLTP7853, which cannot retrive any useful manufacture
information on the internel by this string at present. As the serial number of
the laptop is GLO-G52, while DMI info reports the laptop serial number as
GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.

Some devices managed by this driver automatically set brightness to 0
before entering a suspended state and reset it back to a default
brightness level after the resume:
this has the effect of having the kernel report wrong brightness
status after a sleep, and on some devices (like the Asus RC71L) that
brightness is the intensity of LEDs directly facing the user.
Fix the above issue by setting back brightness to the level it had
before entering a sleep state.

Multiple people reported misbehaving devices and reverting this commit fixes

again, we can try to figure out why he hasn't seen the issues (mismatching
report descriptors?), but for the time being, fix for 6.7 by reverting.

The Glorious Model I mouse has a buggy HID report descriptor for its
keyboard endpoint (used for programmable buttons). For report ID 2, there
is a mismatch between Logical Minimum and Usage Minimum in the array that
reports keycodes.
The offending portion of the descriptor: (from hid-decode)
0x95, 0x05, // Report Count (5) 30
0x75, 0x08, // Report Size (8) 32
0x15, 0x00, // Logical Minimum (0) 34
0x25, 0x65, // Logical Maximum (101) 36
0x05, 0x07, // Usage Page (Keyboard) 38
0x19, 0x01, // Usage Minimum (1) 40
0x29, 0x65, // Usage Maximum (101) 42
0x81, 0x00, // Input (Data,Arr,Abs) 44
This bug shifts all programmed keycodes up by 1. Importantly, this causes
"empty" array indexes of 0x00 to be interpreted as 0x01, ErrorRollOver.
The presence of ErrorRollOver causes the system to ignore all keypresses
from the endpoint and breaks the ability to use the programmable buttons.
Setting byte 41 to 0x00 fixes this, and causes keycodes to be interpreted
correctly.
Also, USB_VENDOR_ID_GLORIOUS is changed to USB_VENDOR_ID_SINOWEALTH,
and a new ID for Laview Technology is added. Glorious seems to be
white-labeling controller boards or mice from these vendors. There isn't a
single canonical vendor ID for Glorious products.

During the probe we add an I2C adapter and as soon as we add that adapter
it may be used for a transfer (e.g via the code in i2cdetect()).
Those transfers are not able to complete and time out. This is because the
HID raw_event callback (mcp2221_raw_event) will not be invoked until the
HID device's 'driver_input_lock' is marked up at the completion of the
probe in hid_device_probe(). This starves the driver of the responses it
is waiting for.
In order to allow the I2C transfers to complete while we are still in the
probe, start the IO once we have completed init of the HID device.
This issue seems to have been seen before and a patch was submitted but
it seems it was never accepted. See:

The process of adding an I2C adapter can invoke I2C accesses on that new
adapter (see i2c_detect()).
Ensure we have set the adapter's driver data to avoid null pointer
dereferences in the xfer functions during the adapter add.
This has been noted in the past and the same fix proposed but not
completed. See:

hid_connect() will call hid_pidff_init() which does
hid_device_io_start() leading to an "io already started" warning.
To fix this call hid_device_io_stop() before calling hid_connect(),
stopping IO means that connect events may be lost while hid_connect()
runs, re-enable IO and move the hidpp_connect_event() work queuing
after the hid_connect().
Note re-enabling IO is also necessary for the g920_get_config()
call later during hidpp_probe().

Drop delayed_work_cb() instead make hidpp_connect_event() the workqueue
function itself.
Besides resulting in a small cleanup this will hopefully also make
it clearer that going forward hidpp_connect_event() should only
be run from a workqueue and not be directly invoked.

There is a connect event race in hidpp_probe() in these 2 lines:
connected = hidpp_root_get_protocol_version(hidpp) == 0;
atomic_set(&hidpp->connected, connected);
Specifically the following can happen:
1. This line from hidpp_probe() is executed:
connected = hidpp_root_get_protocol_version(hidpp) == 0;
and sets connected to false;
2. A connect-event packet is received and does:
atomic_set(&hidpp->connected, true);
3. The next line from hidpp_probe() is executed:
atomic_set(&hidpp->connected, connected);
and sets the atomic_t back to 0 again.
4. hidpp_connect_event() runs and sees the connected device
as disconnected because of this.
To fix this make hidpp_connect_event() query the connection status
of the device itself instead of having it rely on possibly stale
data cached in struct hidpp_device.

Turn hidpp_overwrite_name() into a hidpp_non_unifying_init() helper
which takes care of setting both the name and the serial for non

Move the hidpp_overwrite_name() call to before the connect check, this
puts it at the same place in the probe() order as hidpp_serial_init()
which seems more logical. This should not make a difference since this
is in the non-unifying path and only unifying devices can be probed
in non-connected state.
This is a preparation patch for moving all connected state handling
to hidpp_connect_event().
Doing this before the connect check requires dropping the protocol
version check since protocol_major is not set yet now. Instead
this relies on hidpp_root_get_feature(HIDPP_PAGE_GET_DEVICE_NAME_TYPE)
failing on older devices, just like how hidpp_get_serial() relies on
hidpp_root_get_feature(HIDPP_PAGE_DEVICE_INFORMATION) failing on older
devices. So this again makes the code more consistent.
Also stop printing an error on failure now, since with the proto
version check gone failures are expected to happen on older devices.

The data retrieved by g920_get_config() is only used by hidpp_ff_init().
Now that the hw is kept open till the end of probe() the g920_get_config()
call can be moved to just before hidpp_ff_init() to have all
the HIDPP_QUIRK_CLASS_G920 together in a single place.

For WTP devices which start disconnected (paired with the unifying
receiver, but not connected atm) hidpp_connect_event() takes care
of calling wtp_get_config() when the device later connects.
There is no need to have a separate code path for WTP devices which
are connected at probe() time, these can use the same code-path since
probe() will queue hidpp_connect_event() for those at probe time.
Drop the unnecessary wtp_get_config() call from probe().

hidpp_connect_event()
Calling get_wireless_feature_index() from probe() causes
the wireless_feature_index to only get set for unifying devices which
are already connected at probe() time. It does not get set for devices
which connect later.
Fix this by moving get_wireless_feature_index() to hidpp_connect_event(),
this does not make a difference for devices connected at probe() since
probe() will queue the hidpp_connect_event() for those at probe time.

Commit 91cf9a98ae41 ("HID: logitech-hidpp: make .probe usbhid capable")
makes hidpp_probe() first call hid_hw_start(hdev, 0) to allow IO
without connecting any hid subdrivers (hid-input, hidraw).
This is done to allow to retrieve the device's name and serial number
and store these in hdev->name and hdev->uniq.
Then later on IO was stopped and started again with hid_hw_start(hdev,
HID_CONNECT_DEFAULT) connecting hid-input and hidraw after the name
and serial number have been setup.
Commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary") changed the probe() code to only do the start with
a 0 connect-mask + restart later for unifying devices.
But for non unifying devices hdev->name and hdev->uniq are updated too.
So this change re-introduces the problem for which the start with
a 0 connect-mask + restart later behavior was introduced.
The previous patch in this series changes the unifying path to instead of
restarting IO only call hid_connect() later. This avoids possible issues
with restarting IO seen on non unifying devices.
Revert the change to limit the restart behavior to unifying devices to
fix hdev->name changing after userspace facing devices have already been
registered.

Restarting IO causes 2 problems:
1. Some devices do not like IO being restarted this was addressed in
commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary"), but that change has issues of its own and needs to
be reverted.
2. Restarting IO and specifically calling hid_device_io_stop() causes
received packets to be missed, which may cause connect-events to
get missed.
Restarting IO was introduced in commit 91cf9a98ae41 ("HID: logitech-hidpp:
make .probe usbhid capable") to allow to retrieve the device's name and
serial number and store these in hdev->name and hdev->uniq before
connecting any hid subdrivers (hid-input, hidraw) exporting this info
to userspace.
But this does not require restarting IO, this merely requires deferring
calling hid_connect(). Calling hid_hw_start() with a connect-mask of
0 makes it skip calling hid_connect(), so hidpp_probe() can simply call
hid_connect() later without needing to restart IO.
Remove the stop + restart of IO and instead just call hid_connect() later
to avoid the issues caused by restarting IO.
Now that IO is no longer stopped, hid_hw_close() must be called at the end
of probe() to balance the hid_hw_open() done at the beginning probe().
