2025-02-10platform/x86: alienware-wmi: Refactor LED control methodsKurt Borja
Both WMI devices handled by this module specify a distinct interface for LED control. Previously this module handled this by dynamically adapting arguments passed to wmi_evaluate_method() based on the `interface` global variable. To avoid the use of global variables, and enable the migration to non-deprecated WMI methods, let the WMI drivers define upd_led and upd_brightness operations, which completely replace alienware_update_led() and wmax_brightness(). Also define alienware_wmi_command(), which serves as a wrapper for wmidev_evaluate_method(). This new method is very similar to alienware_wmax_command() but is WMI device agnostic.

2025-02-10platform/x86: alienware-wmi: Add WMI DriversKurt Borja
Add WMI drivers for LEGACY and WMAX devices. This involves moving the platform device registration to a helper function that is now called from the driver's preferred WMI device driver probe. In the case of the WMAX this is done only if `!quirks->thermal` because the newer WMAX interface doesn't support any of the LED features of this driver. This also eliminates the need to check for `quirks->num_zones > 0` inside alienfx_probe(). Only one WMI driver is registered on module initialization to prevent registering a duplicate platform device. Additionally, create_thermal_profile() now takes wmi_device * instead of platform_device *.

Those nodes comprise the so-called data fabric on Zen. This has at least one practical advantage of not having to add a PCI ID each time a new data fabric PCI device releases. Eventually, the lot more uniform provider of data fabric functionality amd_node.c will be used by all the drivers which need it - Smaller cleanups * tag 'x86_misc_for_v6.14_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/amd_node: Use defines for SMN register offsets x86/amd_node: Remove dependency on AMD_NB x86/amd_node: Update __amd_smn_rw() error paths x86/amd_nb: Move SMN access code to a new amd_node driver x86/amd_nb, hwmon: (k10temp): Simplify amd_pci_dev_to_node_id() x86/amd_nb: Simplify function 3 search x86/amd_nb: Use topology info to get AMD node count x86/amd_nb: Simplify root device search x86/amd_nb: Simplify function 4 search x86: Start moving AMD node functionality out of AMD_NB x86/amd_nb: Clean up early_is_amd_nb() x86/amd_nb: Restrict init function to AMD-based systems x86/mtrr: Rename mtrr_overwrite_state() to guest_force_mtrr_state()

There's the usual mix of small improvements and fixes, plus a few new drivers and features. The diffstat includes some DRM changes due to work on HDMI audio. - Allow clocking on each DAI in an audio graph card to be configured separately. - Improved power management for Renesas RZ-SSI. - KUnit testing for the Cirrus DSP framework. - Memory to meory operation support for Freescale/NXP platforms. - Support for pause operations in SOF. - Support for Allwinner suinv F1C100s, Awinc AW88083, Realtek ALC5682I-VE
2025-01-20platform/x86: acer-wmi: Fix initialization of last_non_turbo_profileArmin Wolf
On machines that do not support the balanced profile the value of last_non_turbo_profile is invalid after initialization which might cause the driver to switch to an unsupported platform profile later.

This patch was used to add TAS2781 devices on SPI support in sound/pci/hda. It use ACPI node descript about parameters of TAS2781 on SPI, it like: Scope (_SB.PC00.SPI0) { Device (GSPK) { Name (_HID, "TXNW2781") // _HID: Hardware ID Method (_CRS, 0, NotSerialized) { Name (RBUF, ResourceTemplate () { SpiSerialBusV2 (...) SpiSerialBusV2 (...) } } } } And in platform/x86/serial-multi-instantiate.c, those spi devices will be added into system as a single SPI device, so TAS2781 SPI driver will probe twice for every single SPI device. And driver will also parser mono DSP firmware binary and RCA binary for itself. The code support Realtek as the primary codec. In patch version-10, add multi devices firmware binary support, to compatble with windows driver, they can share same firmware binary.
