2024-02-27platform/x86/fujitsu-laptop: Add battery charge control supportSzilard Fabian
This patch adds battery charge control support on Fujitsu notebooks via the S006 method of the FUJ02E3 ACPI device. With this method it's possible to set charge_control_end_threshold between 50 and 100%. Tested on Lifebook E5411 and Lifebook U728. Sadly I can't test this patch on a dual battery one, but I didn't find any clue about independent battery charge control on dual battery Fujitsu notebooks either. And by that I mean checking the DSDT table of various Lifebook notebooks and reverse engineering FUJ02E3.dll.

2024-01-24platform/x86: remove obsolete calls to ledtrig_audio_getHeiner Kallweit
Since 64f67b5240db ("leds: trigger: audio: Add an activate callback to ensure the initial brightness is set") the audio triggers have an activate callback which sets the LED brightness as soon as the (default) trigger is bound to the LED device. So we can remove the call to ledtrig_audio_get. Positive side effect: There's no code dependency to ledtrig-audio any longer, what allows to remove some Kconfig dependencies.

2023-04-06platform/x86: Add driver for Yoga Tablet Mode switchGergo Koteles
This WMI driver for the tablet mode control switch for Lenovo Yoga notebooks was originally written by Gergo Koteles. The mode is mapped to a SW_TABLET_MODE switch capable input device. Andrew followed the suggestions that were posted in reply to Gergo's RFC patch, and on the v1 & v2 versions of this patch to follow-up and get it merged. Changes from Gergo's RFC: - Refactored obtaining a reference to the EC ACPI device needed for the quirk implementation as suggested by Hans de Goede - Applied small fixes and switched to always registering handles with the driver for automatic cleanup as suggested by Barnabás Pőcze. - Merged the lenovo_ymc_trigger_ec function with the ideapad_trigger_ymc_next_read function since it was no longer external. - Added the word "Tablet" to the driver description to hopefully make it more clear. - Fixed the LENOVO_YMC_QUERY_METHOD ID and the name string for the EC APCI device trigged for the quirk - Triggered the input event on probe so that the initial tablet mode state when the driver is loaded is reported to userspace as suggested by Armin Wolf. - Restricted the permissions of the ec_trigger parameter as suggested by Armin Wolf. Also updated the description. We have tested this on the Yoga 7 14AIL7 for the non-quirk path and on the Yoga 7 14ARB7 which has the firmware bug that requires triggering the embedded controller to send the mode change events. This workaround is also used by the Windows drivers. According to reports at https://github.com/lukas-w/yoga-usage-mode, which uses the same WMI devices, the following models should also work: Yoga C940, Ideapad flex 14API, Yoga 9 14IAP7, Yoga 7 14ARB7, etc. Signed-off-by: Gergo Koteles <soyer@irl.hu> Co-developed-by: Andrew Kallmeyer <kallmeyeras@gmail.com> Signed-off-by: Andrew Kallmeyer <kallmeyeras@gmail.com> Link: https://lore.kernel.org/r/20221004214332.35934-1-soyer@irl.hu/ Link: https://lore.kernel.org/r/20230310041726.217447-1-kallmeyeras@gmail.com/ Link: https://lore.kernel.org/r/20230323025200.5462-1-kallmeyeras@gmail.com/ Tested-by: André Apitzsch <git@apitzsch.eu> Link: https://lore.kernel.org/r/20230329014559.44494-3-kallmeyeras@gmail.com Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2023-03-16backlight: apple_bl: Use acpi_video_get_backlight_type()Hans de Goede
On some MacBooks both the apple_bl and the apple-gmux backlight drivers may be able to export a /sys/class/backlight device. To avoid having 2 backlight devices for one LCD panel until now the apple-gmux driver has been calling apple_bl_unregister() to move the apple_bl backlight device out of the way when it loads. Similar problems exist on other x86 laptops and all backlight drivers which may be used on x86 laptops have moved to using acpi_video_get_backlight_type() to determine whether they should load or not. Switch apple_bl to this model too, so that it is consistent with all the other x86 backlight drivers. Besides code-simplification and consistency this has 2 other benefits: 1) It removes a race during boot where userspace will briefly see an apple_bl backlight and then have it disappear again, leading to e.g.: https://bbs.archlinux.org/viewtopic.php?id=269920 2) This allows user to switch between the drivers by passing acpi_backlight=apple_gmux or acpi_backlight=vendor on the kernel commandline.

C1010 The Peaq C1010 tablet has a special "Dolby" button. This button has a WMI interface, but this is broken in several ways: 1. It only supports polling 2. The value read on polling goes from 0 -> 1 for one poll on both edges of the button, with no way to tell which edge causes the poll to return 1. 3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID). There currently is a WMI driver for this, but it uses several kludges to work around these issues and is not entirely reliable due to 2.

This commit adds the ACPI battery hook which in turns adds the sysfs entries. Because the Toshiba laptops only support two modes (eco or normal), which in testing correspond to 80% and 100% we simply round to the nearest possible level when set. It is possible that Toshiba laptops other than the Z830 has different set points for the charging. If so, a quirk table could be introduced in the future for this.

If mic-mute LED is present by checking WMI ASUS_WMI_DEVID_MICMUTE_LED, we will add a mic-mute LED classdev, asus::micmute, in the asus-wmi driver to control it. The binding of mic-mute LED controls will be swithched with LED trigger.

2022-06-28platform/x86: panasonic-laptop: filter out duplicate volume up/down/mute ↵Hans de Goede
keypresses On some Panasonic models the volume up/down/mute keypresses get reported both through the Panasonic ACPI HKEY interface as well as through the atkbd device. Filter out the atkbd scan-codes for these to avoid reporting presses twice. Note normally we would leave the filtering of these to userspace by mapping the scan-codes to KEY_UNKNOWN through /lib/udev/hwdb.d/60-keyboard.hwdb. However in this case that would cause regressions since we were filtering the Panasonic ACPI HKEY events before, so filter these in the kernel.

2022-06-12platform/x86: Drop the PMC_ATOM Kconfig optionHans de Goede
The def_bool y PMC_ATOM Kconfig option provides a couple of symbols used by the code enabled by the X86_INTEL_LPSS option and it registers some clocks. These clocks are only registered on Bay Trail, Cherry Trail and Brasswell Intel SoCs and kernels targeting these SoCs must always have the X86_INTEL_LPSS option enabled otherwise many things will not work. Building the PMC_ATOM code on kernels which are not targeting the mentioned SoCs and which do not have the X86_INTEL_LPSS enabled is not useful. This means that we can simplify things by replacing the PMC_ATOM Kconfig option in Makefiles with X86_INTEL_LPSS and then drop the option.

2022-02-02platform/x86: serial-multi-instantiate: Add SPI supportStefan Binding
Add support for spi bus in serial-multi-instantiate driver Some peripherals can have either a I2C or a SPI connection to the host (but not both) but use the same HID for both types. So it is not possible to use the HID to determine whether it is I2C or SPI. The driver must check the node to see if it contains I2cSerialBus or SpiSerialBus entries. For backwards-compatibility with the existing nodes I2C is checked first and if such entries are found ONLY I2C devices are created. Since some existing nodes that were already handled by this driver could also contain unrelated SpiSerialBus nodes that were previously ignored, and this preserves that behavior. If there is ever a need to handle a node where both I2C and SPI devices must be instantiated this can be added in future.

2021-12-25platform/x86: x86-android-tablets: New driver for x86 Android tabletsHans de Goede
x86 tablets which ship with Android as (part of) the factory image typically have various problems with their DSDTs. The factory kernels shipped on these devices typically have device addresses and GPIOs hardcoded in the kernel, rather then specified in their DSDT. With the DSDT containing a random collection of devices which may or may not actually be present as well as missing devices which are actually present. This driver, which loads only on affected models based on DMI matching, adds DMI based instantiating of kernel devices for devices which are missing from the DSDT, fixing e.g. battery monitoring, touchpads and/or accelerometers not working. Note the Kconfig help text also refers to "various fixes" ATM there are no such fixes, but there are also known cases where entries are present in the DSDT but they contain bugs, such as missing/wrong GPIOs. The plan is to also add fixes for things like this here in the future. This is the least ugly option to get these devices to fully work and to do so without adding any extra code to the main kernel image (vmlinuz) when built as a module.

The identification is DMI-based with a vendor specific way to tell them apart in a reliable way. Drivers for LEDs and Watchdogs will follow to make use of that platform detection. There is also some code to allow secondary drivers to find GPIO memory, that needs to be in place because the pinctrl drivers do not come up.
