On multi package system, the TPMI SST instance is getting allocated again as the usage counter is not getting incremented. Here the instance is allocated only when the usage count is zero. There is no need to allocate again. Increment usage ID on successful return from isst_if_cdev_register(). Signed-off-by:

Fix issues identified in dytc_profile_refresh identified by lkp-tests. drivers/platform/x86/thinkpad_acpi.c:10538 dytc_profile_refresh() error: uninitialized symbol 'funcmode'. drivers/platform/x86/thinkpad_acpi.c:10531 dytc_profile_refresh() error: uninitialized symbol 'output'. drivers/platform/x86/thinkpad_acpi.c:10537 dytc_profile_refresh() error: uninitialized symbol 'output'. These issues should not lead to real problems in the field as the refresh function should only be called if MMC or PSC mode enabled. But good to fix. Thanks to Dan Carpenter and the lkp-tests project for flagging these. Reported-by:

When core-power configuration or enabled is modified, this is only done for compute dies. But the config must also be set to cores with no CPUs. Without this the configuration is not affective. On displaying config information, allow display for non compute dies also. Signed-off-by:

The system password identification was incorrect. This means that if the password was enabled it wouldn't be detected correctly; and setting it would not work.

Whilst reviewing some documentation from the FW team on using WMI on Lenovo system I noticed that we weren't using Opcode support when changing BIOS settings in the thinkLMI driver. We should be doing this to ensure we're future proof as the old non-opcode mechanism has been deprecated. Tested on X1 Carbon G10 and G11. Signed-off-by:

commit c5ad454a ("platform/x86: intel/pmc/core: Add Meteor Lake support to pmc core driver") was supposed to add support for Meter Lake P/M and mistakenly added support for Meteor Lake S instead. Meteor Lake P/M support was added later and MTL-S support needs to be removed since its currently assigned to the wrong register maps.

Starting from Pink Sardine, number of IP blocks were added to the SoC and the PMFW has the ability to give debug stats on each the IP blocks after a S0ix cycle within part of the SMU metrics table. To differentiate this change, the 's2d_msg_id' is also changed. Add these new capabilities to the driver. Signed-off-by:

PMF driver maintains an internal config store for each PMF feature after the feature init happens. Having a debug mechanism to triage in-field issues w.r.t to mode switch not happening based on the OEM fed values via the ACPI method to PMF driver is becoming the need of the hour. Add support to get more ACPI debug spew guarded by a CONFIG. Co-developed-by:

On the Android yb1-x90f/l models there is not ACPI method to control the keyboard backlight brightness. Instead the second PWM controller is exposed directly to the OS there. Add support for controlling keyboard backlight brightness on the Android model by using the PWM subsystem to directly control the PWM. The Android model also requires explicitly turning the backlight off on suspend, which on the Windows model was done automatically. Signed-off-by:

The Lenovo Yoga Book 1 comes in 2 versions. Version 1: The yb1-x91f/l currently supported by lenovo-yogabook-wmi, which has a WMI interface to deal with toggling the keyboard half between touch-keyboard and wacom-digitizer mode. Version 2: The yb1-x90f/l which is the same hardware shipping with Android as factory OS. This version has a very different BIOS and ACPI tables which lack the WMI interface. Instead the x86-android-tablets.ko code which does devices instantiation for devices missing from ACPI on various x86 Android tablets will instantiate a platform device for the keyboard half touch-kbd/digitizer toggle functionality. This patch adds a platform driver to the lenovo-yogabook code which binds to the platform device instantiated by x86-android-tablets.ko offering touch-kbd/digitizer toggle functionality on the Android model.
