2021-06-16platform/x86: dell-privacy: Add support for Dell hardware privacyPerry Yuan
add support for Dell privacy driver for the Dell units equipped hardware privacy design, which protect users privacy of audio and camera from hardware level. Once the audio or camera privacy mode activated, any applications will not get any audio or video stream when user pressed ctrl+F4 hotkey, audio privacy mode will be enabled, micmute led will be also changed accordingly The micmute led is fully controlled by hardware & EC(embedded controller) and camera mute hotkey is Ctrl+F9. Currently design only emits SW_CAMERA_LENS_COVER event while the camera lens shutter will be changed by EC & HW(hardware) control *The flow is like this: 1) User presses key. HW does stuff with this key (timeout timer is started) 2) WMI event is emitted from BIOS to kernel 3) WMI event is received by dell-privacy 4) KEY_MICMUTE emitted from dell-privacy 5) Userland picks up key and modifies kcontrol for SW mute 6) Codec kernel driver catches and calls ledtrig_audio_set 7) dell-privacy notifies EC, the timeout is cancelled and the HW mute is activated. If the EC is not notified then the HW mic mute will activate when the timeout triggers, just a bit later than with the active ack.

2021-06-16platform/x86: ideapad-laptop: Ignore VPC event bit 10Hans de Goede
VPC event bit 10 gets set on a Yoga 300-11IBR when the EC believes that the device has changed between laptop/tent/stand/tablet mode. The EC relies on getting angle info from 2 accelerometers through a special windows service calling a DSM on the DUAL250E ACPI-device. Linux does not do this, making the laptop/tent/stand/tablet mode info unreliable. Ignore VPC event bit 10 to avoid the warnings triggered by the default case in ideapad_acpi_notify(). Note that the plan for Linux is to have iio-sensor-proxy read the 2 accelerometers and have it provide info about which mode 360° hinges 2-in-1s to the rest of userspace: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/issues/216 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20210523172331.177834-1-hdegoede@redhat.com

G15" The quirks added to asus-nb-wmi for the ASUS ROG Zephyrus G14 and G15 are wrong, they tell the asus-wmi code to use the vendor specific WMI backlight interface. But there is no such interface on these laptops. As a side effect, these quirks stop the acpi_video driver to register since they make acpi_video_get_backlight_type() return acpi_backlight_vendor, leaving only the native AMD backlight driver in place, which is the one we want. This happy coincidence is being replaced with a new quirk in drivers/acpi/video_detect.c which actually sets the backlight_type to acpi_backlight_native fixinf this properly.

TM800A550L tablets The Bay Trail Glavey TM800A550L tablet, which ships with Android installed from the factory, uses a GT912 touchscreen controller which needs to have its firmware uploaded by the OS to work (this is a first for a x86 based device with a Goodix touchscreen controller). Add a touchscreen_dmi entry for this which specifies the filenames to use for the firmware and config files needed for this. Note this matches on a GDIX1001 ACPI HID, while the original DSDT uses a HID of GODX0911. For the touchscreen to work on these devices a DSDT override is necessary to fix a missing IRQ and broken GPIO settings in the ACPI-resources for the touchscreen. This override also changes the HID to the standard GDIX1001 id typically used for Goodix touchscreens.

2021-05-19platform/x86: intel_int0002_vgpio: Only call enable_irq_wake() when using s2idleHans de Goede
Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to the parents IRQ because this was breaking suspend (causing immediate wakeups) on an Asus E202SA. This workaround for the Asus E202SA is causing wakeup by USB keyboard to not work on other devices with Airmont CPU cores such as the Medion Akoya E1239T. In hindsight the problem with the Asus E202SA has nothing to do with Silvermont vs Airmont CPU cores, so the differentiation between the 2 types of CPU cores introduced by the previous fix is wrong. The real issue at hand is s2idle vs S3 suspend where the suspend is mostly handled by firmware. The parent IRQ for the INT0002 device is shared with the ACPI SCI and the real problem is that the INT0002 code should not be messing with the wakeup settings of that IRQ when suspend/resume is being handled by the firmware. Note that on systems which support both s2idle and S3 suspend, which suspend method to use can be changed at runtime. This patch fixes both the Asus E202SA spurious wakeups issue as well as the wakeup by USB keyboard not working on the Medion Akoya E1239T issue. These are both fixed by replacing the old workaround with delaying the enable_irq_wake(parent_irq) call till system-suspend time and protecting it with a !pm_suspend_via_firmware() check so that we still do not call it on devices using firmware-based (S3) suspend such as the Asus E202SA. Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes no sense.

2021-05-19platform/mellanox: mlxbf-tmfifo: Fix a memory barrier issueLiming Sun
The virtio framework uses wmb() when updating avail->idx. It guarantees the write order, but not necessarily loading order for the code accessing the memory. This commit adds a load barrier after reading the avail->idx to make sure all the data in the descriptor is visible. It also adds a barrier when returning the packet to virtio framework to make sure read/writes are visible to the virtio code.

2021-05-19platform/surface: dtx: Fix poll functionMaximilian Luz
The poll function should not return -ERESTARTSYS. Furthermore, locking in this function is completely unnecessary. The ddev->lock protects access to the main device and controller (ddev->dev and ddev->ctrl), ensuring that both are and remain valid while being accessed by clients. Both are, however, never accessed in the poll function. The shutdown test (via atomic bit flags) be safely done without locking, so drop locking here entirely.

2021-05-19platform/surface: aggregator: Do not mark interrupt as sharedMaximilian Luz
Having both IRQF_NO_AUTOEN and IRQF_SHARED set causes request_threaded_irq() to return with -EINVAL (see comment in flag validation in that function). As the interrupt is currently not shared between multiple devices, drop the IRQF_SHARED flag.

2021-05-11platform/x86: hp_accel: Avoid invoking _INI to speed up resumeKai-Heng Feng
hp_accel can take almost two seconds to resume on some HP laptops. The bottleneck is on evaluating _INI, which is only needed to run once. Resolve the issue by only invoking _INI when it's necessary. Namely, on probe and on hibernation restore.

2021-05-11platform/x86: ideapad-laptop: fix method name typoBarnabás Pőcze
"smbc" should be "sbmc". `eval_smbc()` incorrectly called the SMBC ACPI method instead of SBMC. This resulted in partial loss of functionality. Rectify that by calling the correct ACPI method (SBMC), and also rename methods and constants.

2021-05-07treewide: remove editor modelines and cruftMasahiro Yamada
The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.
