2022-09-01platform/x86: asus-wmi: Increase FAN_CURVE_BUF_LEN to 32Luke D. Jones
Fix for TUF laptops returning with an -ENOSPC on calling asus_wmi_evaluate_method_buf() when fetching default curves. The TUF method requires at least 32 bytes space. This also moves and changes the pr_debug() in fan_curve_check_present() to pr_warn() in fan_curve_get_factory_default() so that there is at least some indication in logs of why it fails.

It looks like that on Dell Latitude E6440 is WMI event 0x0012 0x0003 sent when display changes brightness. When it happens kernel prints "dell_wmi: Unknown WMI event type 0x12" message into dmesg.

2022-09-01platform/x86: simatic-ipc: add new model 427GHenning Schild
This adds support for the Siemens Simatic IPC427G. A board which basically works like the 227G added in a previous patch. So all there is to do is to add the station_id and make it take all the 227G branches.

Add GPIO support for Nuvoton NCT6116 chip. Nuvoton SuperIO chips are very similar to the ones from Fintek. In other subsystems they also share drivers and are called a family of drivers. For the GPIO subsystem the only difference is that the direction bit is reversed and that there is only one data bit per pin. On the SuperIO level the logical device is another one. On a chip level we do not have a manufacturer ID to check and also no revision.

The F2 key is marked with a big '?' symbol on the Packard Bell Dot SC, this sends WMID_HOTKEY_EVENTs with a scancode of 0x27 add a mapping for this. 2. Scancode 0x61 is KEY_SWITCHVIDEOMODE. Usually this is a duplicate input event with the "Video Bus" input device events. But on these devices the "Video Bus" does not send events for this key.

2022-08-26platform/x86: msi-laptop: Fix old-ec check for backlight registeringHans de Goede
Commit 2cc6c717799f ("msi-laptop: Port to new backlight interface selection API") replaced this check: if (!quirks->old_ec_model || acpi_video_backlight_support()) pr_info("Brightness ignored, ..."); else do_register(); With: if (quirks->old_ec_model || acpi_video_get_backlight_type() == acpi_backlight_vendor) do_register(); But since the do_register() part was part of the else branch, the entire condition should be inverted. So not only the 2 statements on either side of the || should be inverted, but the || itself should be replaced with a &&. In practice this has likely not been an issue because the new-ec models (old_ec_model==false) likely all support ACPI video backlight control, making acpi_video_get_backlight_type() return acpi_backlight_video turning the second part of the || also false when old_ec_model == false.

2022-08-25platform/x86: asus-wmi: Refactor egpu_enable attributeLuke D. Jones
The settings for these attributes can be read from the device, this is now done instead of reading a stored value from module. The stored value is also removed. This means the simpler asus_wmi_dev_is_present() can be used in *_check_present() - it is not an error for these methods to be missing. The _write() functions have their bodies shifted in to *_store() which simplifies things further. Signed-off-by: Luke D.

client to SP8 Add software nodes for the HID sensor collection and the UCM UCSI HID client to the Surface Pro 8. In contrast to the type-cover devices, these devices are directly attached to the SAM controller, without any hub. This enables support for HID-based sensors, including the ones used for automatic screen rotation, on the Surface Pro 8.
