lenovo-yogabook-wmi: controls the power-state itself and stores this in data->flags so there is no need to poke inside ACPI device internals. This is a preparation patch for making lenovo-yogabook-wmi also work on the Android version of the Yoga Book 1 which does not have a WMI interface to deal with toggling the keyboard half between touch-keyboard and wacom-digitizer mode.

Use the (new) PMIC LED driver for pen icon LED control instead of using custom WMI calls for this. This will also work on the Android version of the Lenovo Yoga Book 1, where there is no WMI interface for this. The dev_id of the lookup is set using dev_name() so that it will also work for both the Windows YB1 WMI-device as well as the Android YB1 platform-device. While at it also move the gpio_lookup to using dev_name() for the dev_id. Note this also removes the need to turn of the LED during suspend since the PMIC LED driver now already does that.

Ensure that both the keyboard touchscreen and the digitizer have their driver bound after remove(). Without this modprobing lenovo-yogabook-wmi after a rmmod fails because lenovo-yogabook-wmi defers probing until both devices have their driver bound.

When yogabook_wmi_remove() runs yogabook_wmi_work might still be running and using the devices which yogabook_wmi_remove() puts. To avoid this move to explicitly cancelling the work rather then using devm_work_autocancel(). This requires also making the yogabook_backside_hall_irq handler non devm managed, so that it cannot re-queue the work while yogabook_wmi_remove() runs.

Currently, the WMI driver core knows how many instances of a given WMI object exist, but WMI drivers cannot access this information. At the same time, some current and upcoming WMI drivers want to have access to this information. Add wmi_instance_count() and wmidev_instance_count() to allow WMI drivers to get the number of WMI object instances. Signed-off-by:

Modify the gpio_keys support in x86_android_tablet_init() for tablets which have more then 1 key/button which needs to be handled by the gpio_keys driver. This requires copying over the struct gpio_keys_button from the x86_gpio_button struct array to a new gpio_keys_button struct array, as an added benefit this allows marking the per model x86_gpio_button arrays __initconst so that they all can be freed after module init().

The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module. Note the Ares 8A is the Cherry Trail (CHT) model, the regular Ares 8 is Bay Trail (BYT) based and was already supported. This also updates the comments for the BYT model to point out this is the BYT model. Signed-off-by:

Since commit 5adc4093 ("ACPI: x86: Introduce an acpi_quirk_skip_gpio_event_handlers() helper") the ACPI GPIO code will not register any GPIO event handlers at all for devices which have the ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS set in their DMI table entry in drivers/acpi/x86/utils.c . This includes the Nextbook Ares 8 and the Asus ME176C and TF103C models, so x86-android-tablets no longer needs to disable the GPIO event handlers on these, since they have never been registered at all.

Previously, some support for certain keys on the HP keyboard has been added already in commit 3ee5447b ("platform/x86: hp-wmi: Handle Omen Key event"), however this as tested did not allow even the fn+esc key on my HP Envy which uses the same keycode on my HP Envy x360 laptop to work --the keycode rather than being passed in as a separate int from WMI, was being passed in as the event_data for the HPWMI_OMEN_KEY event. This patch, as tested was able to properly get the keycode for fn+esc, and for fn+f12 which is supposed to be a programmable key according to HP's keyboard diagram and is thus mapped to KEY_PROG2. The fn+f8 key combination (mute microphone) was a standard HPWMI_BEZEL_BUTTON key, however it did not previously have an entry in the sparse keymap. This patch preserves the original HPWMI_OMEN_KEY behavior for laptops that use it by only taking the keycode from the event_data only when the event_data is nonzero. Signed-off-by:

Previously, when the camera toggle switch was hit, the hp-wmi driver would report an invalid event code. By adding a case for that in the event handling switch statement we can eliminate that error code and enable a framework for potential further kernel handling of that key. This change was tested on my HP Envy x360 15-ey0023dx laptop, but it would likely work for any HP laptop with a camera toggle button. Now we emit an SW_CAMERA_LENS_COVER event, on a device that gets created on the first such event so as to not report incorrectly the state of the camera shutter before we can know its state.

The new generation of CPUs have granular control at a cluster level. Each package/die can have multiple power domains, which further can have multiple fabric clusters. The TPMI interface allows control at fabric cluster level. Use the updated uncore sysfs feature to expose controls at cluster level. At each cluster level there is a control for maximum and minimum uncore frequency. Also present current uncore frequency at a cluster level. Signed-off-by:

An SoC can contain multiple power domains with individual or collection of mesh partitions. This partition is called fabric cluster. Certain type of meshes will need to run at the same frequency, they will be placed in the same fabric cluster. Benefit of fabric cluster is that it offers a scalable mechanism to deal with partitioned fabrics in a SoC. The current sysfs interface supports control at package and die level. This interface is not enough to support more granular control at fabric cluster level. SoCs with the support of TPMI (Topology Aware Register and PM Capsule Interface), can have multiple power domains. Each power domain can contain one or more fabric clusters. To support such granular controls, enhance uncore common to optionally create new directories to provide controls at fabric cluster level. It is also important to have flexibility to change granularity for future version of SoCs. If the directory name contains scope like: "package_*_die_*_power_domain_*_cluster_*", then this is not expandable. The cpufreq policies also have different scopes. There the scope of the policy (affected_cpus) specified by attributes inside each policy. So, follow the same model for uncore frequency scaling sysfs as: "sys/devices/system/cpu/cpufreq/policy*" Allow client drivers to optionally support granular control for each fabric cluster. Here, the directory name will be "uncore" suffixed with an unique instance number. For example: uncore00, uncore01 etc. Attributes in the directory identify package id, power domain and fabric cluster id. This interface is expandable even if some new level of granularity is introduced. A new sysfs attribute can identify new level. For compatibility with the existing sysfs and provide easy way to set limits for each fabric cluster in the package/die, the existing control at package/die levels are still provided. For majority of users, this is an easy approach. For example: On a single package/die system, with three power domains and one fabric cluster per power domain: $tree -L 2 /sys/devices/system/cpu/intel_uncore_frequency/ /sys/devices/system/cpu/intel_uncore_frequency/ ├── package_00_die_00 │ ├── current_freq_khz │ ├── initial_max_freq_khz │ ├── initial_min_freq_khz │ ├── max_freq_khz │ └── min_freq_khz ├── uncore00 │ ├── current_freq_khz │ ├── domain_id │ ├── fabric_cluster_id │ ├── initial_max_freq_khz │ ├── initial_min_freq_khz │ ├── max_freq_khz │ ├── min_freq_khz │ └── package_id ├── uncore01 │ ├── current_freq_khz │ ├── domain_id │ ├── fabric_cluster_id │ ├── initial_max_freq_khz │ ├── initial_min_freq_khz │ ├── max_freq_khz │ ├── min_freq_khz │ └── package_id └── uncore02 ├── current_freq_khz ├── domain_id ├── fabric_cluster_id ├── initial_max_freq_khz ├── initial_min_freq_khz ├── max_freq_khz ├── min_freq_khz └── package_id The attribute for cluster id is "fabric_cluster_id" instead of just "cluster_id" is to avoid confusion with usage of term clusters in other part of the Linux kernel.

Implement support of uncore frequency control via TPMI (Topology Aware Register and PM Capsule Interface). This driver provides the similar functionality as the current uncore frequency driver using MSRs. The hardware interface to read/write is basically substitution of MSR 0x620 and 0x621. There are specific MMIO offset and bits to get/set minimum and maximum uncore ratio, similar to MSRs. The scope of the uncore MSRs is package/die. But new generation of CPUs have more granular control at a cluster level. Each package/die can have multiple power domains, which further can have multiple clusters. The TPMI interface allows control at cluster level. The primary use case for uncore sysfs is to set maximum and minimum uncore frequency to reduce power consumption or latency. The current uncore sysfs control is per package/die. This is enough for the majority of users as workload will move to different power domains as it moves between different CPUs. The current uncore sysfs provides controls at package/die level. When user sets maximum/minimum limits, the driver sets the same limits to each cluster. Here number of power domains = number of resources in this aux device. There are offsets and bits to discover number of clusters and offset for each cluster level controls.

There has been a lot of confusion around which platform profiles are supported on various platforms and it would be useful to have a debug method to be able to override the profile mode that is selected.

I had incorrectly thought that PSC profiles were not usable on Intel platforms so had blocked them in the driver initialistion. This broke platform profiles on the T490. After discussion with the FW team PSC does work on Intel platforms and should be allowed. Note - it's possible this may impact other platforms where it is advertised but special driver support that only Windows has is needed. But if it does then they will need fixing via quirks. Please report any issues to me so I can get them addressed - but I haven't found any problems in testing...yet Fixes: bce6243f ("platform/x86: thinkpad_acpi: do not use PSC mode on Intel platforms") Link: https://bugzilla.redhat.com/show_bug.cgi?id=2177962 Cc: stable@vger.kernel.org Signed-off-by:
