* ACPI: EC: make EC support compile-time conditionalArnd Bergmann2024-10-241-10/+12
| | | | | | | | | | | | | | | | | | | | | | | The embedded controller code is mainly used on x86 laptops and cannot work without PC style I/O port access. Make this a user-visible configuration option that is default enabled on x86 but otherwise disabled, and that can never be enabled unless CONFIG_HAS_IOPORT is also available. The empty stubs in internal.h help ignore the EC code in configurations that don't support it. In order to see those stubs, the sbshc code also has to include this header and drop duplicate declarations. All the direct callers of ec_read/ec_write already had an x86 dependency and now also need to depend on APCI_EC.

* platform/x86: serial-multi-instantiate: Don't require both I2C and SPIRichard Fitzgerald2024-08-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Change the Kconfig dependency so that it doesn't require both I2C and SPI subsystems to be built. Make a few small changes to the code so that the code for a bus is only called if the bus is being built. When SPI support was added to serial-multi-instantiate it created a dependency that both CONFIG_I2C and CONFIG_SPI must be enabled. Typically they are, but there's no reason why this should be a requirement. A specific kernel build could have only I2C devices or only SPI devices. It should be possible to use serial-multi-instantiate if only I2C or only SPI is enabled. The dependency formula used is: depends on (I2C && !SPI) || (!I2C && SPI) || (I2C && SPI) The advantage of this approach is that if I2C=m or SPI=m then SERIAL_MULTI_INSTANTIATE is limited to n/m.

* platform/x86: ideapad-laptop: move ymc_trigger_ec from lenovo-ymcGergo Koteles2024-08-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | Some models need to trigger the EC after each YMC event for the yoga mode control to work properly. EC triggering consist of a VPC call from the lenovo-ymc module. Except for this, all VPC calls are in the ideapad-laptop module. Since ideapad-laptop has a notification chain, a new YMC_EVENT action can be added and triggered from the lenovo-ymc module. Then the ideapad-laptop can trigger the EC. If the triggering is in the ideapad-laptop module, then the ec_trigger module parameter should be there as well. Move the ymc_trigger_ec functionality and the ec_trigger module parameter to the ideapad-laptop module.

* platform/x86: Add new MeeGoPad ANX7428 Type-C Cross Switch driverHans de Goede2024-05-151-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some MeeGoPad top-set boxes have an ANX7428 Type-C Switch for USB3.1 Gen 1 and DisplayPort over Type-C alternate mode support. The ANX7428 has a microcontroller which takes care of the PD negotiation and automatically sets the builtin Crosspoint Switch to send the right signal to the 4 highspeed pairs of the Type-C connector. It also takes care of HPD and AUX channel routing for DP alternate mode. IOW the ANX7428 operates fully autonomous and to the x5-Z8350 SoC things look like there simple is a USB-3 Type-A connector and a separate DisplayPort connector. Except that the BIOS does not power on the ANX7428 at boot (meh). Add a driver to power on the ANX7428. This driver is added under drivers/platform/x86 rather than under drivers/usb/typec for 2 reasons: 1. This driver is specifically written to work with how the ANX7428 is described in the ACPI tables of the MeeGoPad x86 (Cherry Trail) devices. 2. This driver only powers on the ANX7428 and does not do anything wrt its Type-C functionality. It should be possible to tell the controller which data- and/or power-role to negotiate and to swap the role(s) after negotiation but the MeeGoPad top-set boxes always draw their power from a separate power-connector and they only support USB host-mode. So this functionality is unnecessary and due to lack of documentation this is tricky to support.

| | | | | | | | | | | | | | | | | | | | | | Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist. The driver was tested by the user who created the github issue.

| | | | | | | | | | | | | | | | | 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.

* platform/x86: Add driver for Yoga Tablet Mode switchGergo Koteles2023-04-061-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

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. Replace the unreliable WMI driver by using the x86-android-tablets code to instantiate a gpio_keys device for this.

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.
