96e08fb285 platform/x86: intel-vbtn: Update tablet mode switch at end of probe
[ Upstream commit 434e5781d8 ]

ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as
follow:

   Device (VGBI)
   {
       Name (_HID, EisaId ("INT33D6") ...
       Name (VBDS, Zero)
       Method (_STA, 0, Serialized)  // _STA: Status ...
       Method (VBDL, 0, Serialized)
       {
           PB1E |= 0x20
           VBDS |= 0x40
       }
       Method (VGBS, 0, Serialized)
       {
           Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */
       }
       ...
    }

By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set)
only after method VBDL is executed.

Since VBDL is now evaluated in the probe routine later, after the device
is registered, the retrieved value of VBDS was still 0 ("tablet mode")
when setting up the virtual switch.

Make sure to evaluate VGBS after VBDL, to ensure the
convertible boots in clamshell mode, the expected default.

3fe68ad2d3 platform/x86/intel/hid: Don't wake on 5-button releases
[ Upstream commit 5864e479ca ]

If, for example, the power button is configured to suspend, holding it
and releasing it after the machine has suspended, will wake the machine.

Also on some machines, power button release events are sent during
hibernation, even if the button wasn't used to hibernate the machine.
This causes hibernation to be aborted.

aec7d25b49 platform/x86: p2sb: On Goldmont only cache P2SB and SPI devfn BAR
On Goldmont p2sb_bar() only ever gets called for 2 devices, the actual P2SB
devfn 13,0 and the SPI controller which is part of the P2SB, devfn 13,2.

But the current p2sb code tries to cache BAR0 info for all of
devfn 13,0 to 13,7 . This involves calling pci_scan_single_device()
for device 13 functions 0-7 and the hw does not seem to like
pci_scan_single_device() getting called for some of the other hidden
devices. E.g. on an ASUS VivoBook D540NV-GQ065T this leads to continuous
ACPI errors leading to high CPU usage.

Fix this by only caching BAR0 info and thus only calling
pci_scan_single_device() for the P2SB and the SPI controller.

427c70dec7 platform/x86: thinkpad_acpi: Only update profile if successfully converted
Randomly a Lenovo Z13 will trigger a kernel warning traceback from this
condition:

```
if (WARN_ON((profile < 0) || (profile >= ARRAY_SIZE(profile_names))))
```

This happens because thinkpad-acpi always assumes that
convert_dytc_to_profile() successfully updated the profile. On the
contrary a condition can occur that when dytc_profile_refresh() is called
the profile doesn't get updated as there is a -EOPNOTSUPP branch.

Catch this situation and avoid updating the profile. Also log this into
dynamic debugging in case any other modes should be added in the future.

84c16d01ff platform/x86: intel-vbtn: Stop calling "VBDL" from notify_handler
Commit 14c200b7ca ("platform/x86: intel-vbtn: Fix missing
tablet-mode-switch events") causes 2 issues on the ThinkPad X1 Tablet Gen2:

1. The ThinkPad will wake up immediately from suspend
2. When put in tablet mode SW_TABLET_MODE reverts to 0 after about 1 second

Both these issues are caused by the "VBDL" ACPI method call added
at the end of the notify_handler.

And it never became entirely clear if this call is even necessary to fix
the issue of missing tablet-mode-switch events on the Dell Inspiron 7352.

Drop the "VBDL" ACPI method call again to fix the 2 issues this is
causing on the ThinkPad X1 Tablet Gen2.

dc5afd720f platform/x86: Add new get_serdev_controller() helper
In some cases UART attached devices which require an in kernel driver,
e.g. UART attached Bluetooth HCIs are described in the ACPI tables
by an ACPI device with a broken or missing UartSerialBusV2() resource.

This causes the kernel to create a /dev/ttyS# char-device for the UART
instead of creating an in kernel serdev-controller + serdev-device pair
for the in kernel driver.

The quirk handling in acpi_quirk_skip_serdev_enumeration() makes the kernel
create a serdev-controller device for these UARTs instead of a /dev/ttyS#.

Instantiating the actual serdev-device to bind to is up to pdx86 code,
so far this was handled by the x86-android-tablets code. But since
commit b286f4e87e ("serial: core: Move tty and serdev to be children of
serial core port device") the serdev-controller device has moved in the
device hierarchy from (e.g.) /sys/devices/pci0000:00/8086228A:00/serial0 to
/sys/devices/pci0000:00/8086228A:00/8086228A:00:0/8086228A:00:0.0/serial0 .

This makes this a bit trickier to do and another driver is in the works
which will also need this functionality.

Add a new helper to get the serdev-controller device, so that the new
code for this can be shared.

After commit 4014ae236b ("platform/x86: x86-android-tablets: Stop using

the Lenovo Yogabook1 X90 stopped working with the following error:

 Goodix-TS i2c-goodix_ts: error -EBUSY: Failed to get irq GPIO

The problem is that when getting the IRQ for instantiated i2c_client-s
from a GPIO (rather then using an IRQ directly from the IOAPIC),
x86_acpi_irq_helper_get() now properly requests the GPIO, which disallows
other drivers from requesting it. Normally this is a good thing, but
the goodix touchscreen also uses the IRQ as an output during reset
to select which of its 2 possible I2C addresses should be used.

Add a new free_gpio flag to struct x86_acpi_irq_data to deal with this
and release the GPIO after getting the IRQ in this special case.

dbcbfd662a platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI names
On some devices the ACPI name of the touchscreen is e.g. either
MSSL1680:00 or MSSL1680:01 depending on the BIOS version.

This happens for example on the "Chuwi Hi8 Air" tablet where the initial
commit's ts_data uses "MSSL1680:00" but the tablets from the github issue
and linux-hardware.org probe linked below both use "MSSL1680:01".

Replace the strcmp() match on ts_data->acpi_name with a strstarts()
check to allow using a partial match on just the ACPI HID of "MSSL1680"
and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly
to fix the touchscreen not working on models where it is "MSSL1680:01".

Note this drops the length check for I2C_NAME_SIZE. This never was
necessary since the ACPI names used are never more then 11 chars and
I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long
before reaching I2C_NAME_SIZE.

8cbc756b80 platform/mellanox: mlxbf-tmfifo: Drop Tx network packet when Tx TmFIFO is full
Starting from Linux 5.16 kernel, Tx timeout mechanism was added
in the virtio_net driver which prints the "Tx timeout" warning
message when a packet stays in Tx queue for too long. Below is an
example of the reported message:

"[494105.316739] virtio_net virtio1 tmfifo_net0: TX timeout on
queue: 0, sq: output.0, vq: 0×1, name: output.0, usecs since
last trans: 3079892256".

This issue could happen when external host driver which drains the
FIFO is restared, stopped or upgraded. To avoid such confusing
"Tx timeout" messages, this commit adds logic to drop the outstanding
Tx packet if it's not able to transmit in two seconds due to Tx FIFO
full, which can be considered as congestion or out-of-resource drop.

This commit also handles the special case that the packet is half-
transmitted into the Tx FIFO. In such case, the packet is discarded
with remaining length stored in vring->rem_padding. So paddings with
zeros can be sent out when Tx space is available to maintain the
integrity of the packet format. The padded packet will be dropped on
the receiving side.

5913320eb0 platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe
p2sb_bar() unhides P2SB device to get resources from the device. It
guards the operation by locking pci_rescan_remove_lock so that parallel
rescans do not find the P2SB device. However, this lock causes deadlock
when PCI bus rescan is triggered by /sys/bus/pci/rescan. The rescan
locks pci_rescan_remove_lock and probes PCI devices. When PCI devices
call p2sb_bar() during probe, it locks pci_rescan_remove_lock again.
Hence the deadlock.

To avoid the deadlock, do not lock pci_rescan_remove_lock in p2sb_bar().
Instead, do the lock at fs_initcall. Introduce p2sb_cache_resources()
for fs_initcall which gets and caches the P2SB resources. At p2sb_bar(),
refer the cache and return to the caller.

Before operating the device at P2SB DEVFN for resource cache, check
that its device class is PCI_CLASS_MEMORY_OTHER 0x0580 that PCH
specifications define. This avoids unexpected operation to other devices
at the same DEVFN.

416de0246f platform/x86: intel-uncore-freq: Fix types in sysfs callbacks
When booting a kernel with CONFIG_CFI_CLANG, there is a CFI failure when
accessing any of the values under
/sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00:

  $ cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/max_freq_khz
  fish: Job 1, 'cat /sys/devices/system/cpu/int…' terminated by signal SIGSEGV (Address boundary error)

  $ sudo dmesg &| grep 'CFI failure'
  [  170.953925] CFI failure at kobj_attr_show+0x19/0x30 (target: show_max_freq_khz+0x0/0xc0 [intel_uncore_frequency_common]; expected type: 0xd34078c5

The sysfs callback functions such as show_domain_id() are written as if
they are going to be called by dev_attr_show() but as the above message
shows, they are instead called by kobj_attr_show(). kCFI checks that the
destination of an indirect jump has the exact same type as the prototype
of the function pointer it is called through and fails when they do not.

These callbacks are called through kobj_attr_show() because
uncore_root_kobj was initialized with kobject_create_and_add(), which
means uncore_root_kobj has a ->sysfs_ops of kobj_sysfs_ops from
kobject_create(), which uses kobj_attr_show() as its ->show() value.

The only reason there has not been a more noticeable problem until this
point is that 'struct kobj_attribute' and 'struct device_attribute' have
the same layout, so getting the callback from container_of() works the
same with either value.

Change all the callbacks and their uses to be compatible with
kobj_attr_show() and kobj_attr_store(), which resolves the kCFI failure
and allows the sysfs files to work properly.

29e473f4b5 platform/x86: wmi: Fix notify callback locking
When an legacy WMI event handler is removed, an WMI event could
have called the handler just before it was removed, meaning the
handler could still be running after wmi_remove_notify_handler()
returns.
Something similar could also happens when using the WMI bus, as
the WMI core might still call the notify() callback from an WMI
driver even if its remove() callback was just called.

Fix this by introducing a rw semaphore which ensures that the
event state of a WMI device does not change while the WMI core
is handling an event for it.

bd736f38c0 TTY/Serial changes for 6.8-rc1
Here is the big set of tty and serial driver changes for 6.8-rc1.
 
 As usual, Jiri has a bunch of refactoring and cleanups for the tty core
 and drivers in here, along with the usual set of rs485 updates (someday
 this might work properly...)  Along with those, in here are changes for:
   - sc16is7xx serial driver updates
   - platform driver removal api updates
   - amba-pl011 driver updates
   - tty driver binding updates
   - other small tty/serial driver updates and changes
 
 All of these have been in linux-next for a while with no reported
 issues.

296455ade1 Char/Misc and other Driver changes for 6.8-rc1
Here is the big set of char/misc and other driver subsystem changes for
 6.8-rc1.  Lots of stuff in here, but first off, you will get a merge
 conflict in drivers/android/binder_alloc.c when merging this tree due to
 changing coming in through the -mm tree.
 
 The resolution of the merge issue can be found here:
 	https://lore.kernel.org/r/20231207134213.25631ae9@canb.auug.org.au
 or in a simpler patch form in that thread:
 	https://lore.kernel.org/r/ZXHzooF07LfQQYiE@google.com
 
 If there are issues with the merge of this file, please let me know.
 
 Other than lots of binder driver changes (as you can see by the merge
 conflicts) included in here are:
  - lots of iio driver updates and additions
  - spmi driver updates
  - eeprom driver updates
  - firmware driver updates
  - ocxl driver updates
  - mhi driver updates
  - w1 driver updates
  - nvmem driver updates
  - coresight driver updates
  - platform driver remove callback api changes
  - tags.sh script updates
  - bus_type constant marking cleanups
  - lots of other small driver updates
 
 All of these have been in linux-next for a while with no reported issues
 (other than the binder merge conflict.)

42bff4d0f9 pwm: Changes for v6.8-rc1
This contains a bunch of cleanups and simplifications across the board,
 as well as a number of small fixes.
 
 Perhaps the most notable change here is the addition of an API that
 allows PWMs to be used in atomic contexts, which is useful when time-
 critical operations are involved, such as using a PWM to generate IR
 signals.
 
 Finally, I have decided to step down as PWM subsystem maintainer. Due to
 other responsibilities I have lately not been able to find the time that
 the subsystem deserves and Uwe, who has been helping out a lot for the
 past few years and has many things planned for the future, has kindly
 volunteered to take over. I have no doubt that he will be a suitable
 replacement.

5b9b41617b Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
   warning that was added in 6.2.
 
 - Some reworking of the Documentation/process front page to, hopefully,
   make it more useful.
 
 - Various kernel-doc tweaks to, for example, make it deal properly with
   __counted_by annotations.
 
 - We have also restored a warning for documentation of nonexistent
   structure members that disappeared a while back.  That had the delightful
   consequence of adding some 600 warnings to the docs build.  A sustained
   effort by Randy, Vegard, and myself has addressed almost all of those,
   bringing the documentation back into sync with the code.  The fixes are
   going through the appropriate maintainer trees.
 
 - Various improvements to the HTML rendered docs, including automatic links
   to Git revisions and a nice new pulldown to make translations easy to
   access.
 
 - Speaking of translations, more of those for Spanish and Chinese.
 
 ...plus the usual stream of documentation updates and typo fixes.

Merge tag 'docs-6.8' of git://git.lwn.net/linux

Pull documentation update from Jonathan Corbet:
 "Another moderately busy cycle for documentation, including:

   - The minimum Sphinx requirement has been raised to 2.4.4, following
     a warning that was added in 6.2

   - Some reworking of the Documentation/process front page to,
     hopefully, make it more useful

   - Various kernel-doc tweaks to, for example, make it deal properly
     with __counted_by annotations

   - We have also restored a warning for documentation of nonexistent
     structure members that disappeared a while back. That had the
     delightful consequence of adding some 600 warnings to the docs
     build. A sustained effort by Randy, Vegard, and myself has
     addressed almost all of those, bringing the documentation back into
     sync with the code. The fixes are going through the appropriate
     maintainer trees

   - Various improvements to the HTML rendered docs, including automatic
     links to Git revisions and a nice new pulldown to make translations
     easy to access

   - Speaking of translations, more of those for Spanish and Chinese

  ... plus the usual stream of documentation updates and typo fixes"
