2021-02-02platform/x86: thinkpad_acpi: Add platform profile supportMark Pearson
Add support to thinkpad_acpi for Lenovo platforms that have DYTC version 5 support or newer to use the platform profile feature. This will allow users to determine and control the platform modes between low-power, balanced operation and performance modes.

The previous commit adding new sysfs for keyboard language has warning and few code correction has to be done as per new review comments. Below changes has been addressed in this version: - corrected warning. Many thanks to kernel test robot <lkp@intel.com> for reporting and determining this warning. - used sysfs_emit_at() API instead of strcat. - sorted keyboard language array. - removed unwanted space and corrected sentences.

2021-02-02platform/x86: thinkpad_acpi: Don't register keyboard_lang unnecessarilyHans de Goede
All recent ThinkPad BIOS-es support the GSKL method used to query the keyboard-layout used by the ECFW for the SHIFT + other-key key-press emulation for special keys such as e.g. the '=', '(' and ')' keys above the numpad on 15" models. So just checking for the method is not a good indicator of the model supporting getting/setting the keyboard_lang. On models where this is not supported GSKL succeeds, but it returns METHOD_ERR in the returned integer to indicate that this is not supported on this model. Add a check for METHOD_ERR and return -ENODEV if it is set to avoid registering a non-working keyboard_lang sysfs-attr on models where this is not supported.

2021-01-25platform/x86: thinkpad_acpi: set keyboard languageNitin Joshi
This patch is to create sysfs entry for setting keyboard language using ASL method. Some thinkpads models like T580 , T590 , T15 Gen 1 etc. has "=", "(',")" numeric keys, which are not displaying correctly, when keyboard language is other than "english". This patch fixes this issue by setting keyboard language to ECFW.

2020-11-25platform/x86: thinkpad_acpi: Add palm sensor supportMark Pearson
Add support to thinkpad_acpi for returning the status of the palm sensor. This patch builds on the work done previously for the input device implementation (which was not needed). Both lap and palm sensor are using sysfs and they are combined into the proxsensor block. Note: On some platforms, because of an issue in the HW implementation, the palm sensor presence may be incorrectly advertised as always enabled even if a palm sensor is not present. The palm sensor is intended for WWAN transmission power control and should be available and correct on all WWAN enabled systems. It is not recommended to use this interface for other use cases.

2020-11-09platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11eHans de Goede
The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node. This setup relies on a Windows service which reads both accelerometers and then calculates the angle between the 2 halves to determine laptop / tent / tablet mode and then reports the calculated mode back to the EC by calling special ACPI methods on the BOSC0200 node. The bmc150 iio driver does not support this (it involves double calculations requiring sqrt and arccos so this really needs to be done in userspace), as a result of this on the Yoga 11e the thinkpad_acpi code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting SW_TABLET_MODE=0 causes GNOME to: 1. Not show the onscreen keyboard when a text-input field is focussed with the touchscreen. 2. Disable accelerometer based auto display-rotation. This makes sense when in laptop-mode but not when in tablet-mode. But since for the Yoga 11e the thinkpad_acpi code always reports SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode. Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models to fix this. Note there are plans for userspace to support 360 degree hinges style 2-in-1s with 2 accelerometers and figure out the mode by itself, see: 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/20201106140130.46820-1-hdegoede@redhat.com

2020-04-27platform/x86: thinkpad_acpi: Add support for dual fan controlLars Hofhansl
This adds dual fan control for the following models: P50, P51, P52, P70, P71, P72, P1 gen1, P2 gen2, X1E gen1 and X1E gen2. Both fans are controlled together as if they were a single fan. Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50. The patch is defensive, it adds only specific supported machines, and falls back to the old behavior if both fans cannot be controlled. Background: I tested the BIOS default behavior on my X1E gen2 and both fans are always changed together. So rather than adding controls for each fan, this controls both fans together as the BIOS would do. This was inspired by a discussion on dual fan support for the thinkfan tool (see link below). All BIOS IDs are taken from there. The X1E gen2 ID is verified on my machine. Thanks to GitHub users voidworker and civic9 for the earlier patches and BIOS IDs, and to users peter-stoll and sassman for testing the patch on their machines.

2019-07-29platform/x86: thinkpad_acpi: Use kmemdup rather than duplicating its ↵Fuqian Huang
implementation kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy. Signed-off-by: Fuqian Huang <huangfq.daxian@gmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Since we've switched to the LED trigger for binding with HD-audio, we can drop the exported function as well as the whole linux/thinkpad_acpi.h. The own TPACPI_LED_MUTE and TPACPI_LED_MICMUTE definitions are replaced with the identical ones for LEDS, i.e. LED_AUDIO_MUTE and LED_AUDIO_MICMUTE, respectively.

2018-11-28platform/x86: thinkpad_acpi: Add audio mute LED classdev supportTakashi Iwai
In the upcoming change, the binding of audio mute / mic-mute LED controls will be switched with LED trigger. This patch is the last piece of preparation: adding the audio mute / mic-mute LED class devices to thinkpad_acpi driver. Two devices, platform::mute and platform::micmute, will be added for controlling the mute LED and mic-mute LED, respectively. The new prefix "platform" is the suggestion by upstream for indicating the generic laptop attribute. Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO unconditionally. Strictly speaking, these aren't 100% mandatory, but leaving these manual selections would lead to a functional regression easily once after converting from the dynamic symbol binding to the LEDs trigger in a later patch.

The driver notifies user on hotplug device signal receiving. - ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. - ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. - Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button. * tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86: (47 commits) platform/x86: acer-wmi: Silence "unsupported" message a bit platform/x86: intel_punit_ipc: fix build errors platform/x86: ideapad: Add Y520-15IKBM and Y720-15IKBM to no_hw_rfkill platform/x86: asus-nb-wmi: Add keymap entry for lid flip action on UX360 platform/x86: acer-wmi: refactor function has_cap platform/x86: thinkpad_acpi: Fix multi-battery bug platform/x86: thinkpad_acpi: extend battery quirk coverage platform/x86: touchscreen_dmi: Add info for the Cube KNote i1101 tablet platform/x86: mlx-platform: Fix copy-paste error in mlxplat_init() platform/x86: mlx-platform: Remove unused define platform/x86: mlx-platform: Change mlxreg-io configuration for MSN274x systems Documentation/ABI: Add new attribute for mlxreg-io sysfs interfaces platform/x86: mlx-platform: Allow mlxreg-io driver activation for more systems platform/x86: mlx-platform: Add ASIC hotplug device configuration platform/mellanox: mlxreg-hotplug: Add hotplug hwmon uevent notification platform/mellanox: mlxreg-hotplug: Improve mechanism of ASIC health discovery platform/x86: mlx-platform: Add mlxreg-fan platform driver activation platform/x86: dell-laptop: Fix backlight detection platform/x86: toshiba_acpi: Fix defined but not used build warnings platform/x86: thinkpad_acpi: Support battery quirk ...
