2024-07-02platform/x86: toshiba_acpi: Fix quickstart quirk handlingArmin Wolf
The global hci_hotkey_quickstart quirk flag is tested in toshiba_acpi_enable_hotkeys() before the quirk flag is properly initialized based on SMBIOS data. This causes the quirk to be applied to all models, some of which behave erratically as a result. Fix this by initializing the global quirk flags during module initialization before registering the ACPI driver. This also allows us to mark toshiba_dmi_quirks[] as __initconst.

2024-06-24platform/x86: lg-laptop: Use ACPI device handle when evaluating WMAB/WMBBArmin Wolf
On the LG Gram 16Z90S, the WMAB and WMBB ACPI methods are not mapped under \XINI, but instead are mapped under \_SB.XINI. The reason for this is that the LGEX0820 ACPI device used by this driver is mapped at \_SB.XINI, so the ACPI methods where moved as well to appear below the LGEX0820 ACPI device. Fix this by using the ACPI handle from the ACPI device when evaluating both methods.

2024-06-03platform/x86: dell-smbios: Fix wrong token data in sysfsArmin Wolf
When reading token data from sysfs on my Inspiron 3505, the token locations and values are wrong. This happens because match_attribute() blindly assumes that all entries in da_tokens have an associated entry in token_attrs. This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute(). Fix this by defining an extra struct for each pair of token attributes and use container_of() to retrieve token information. Tested on a Dell Inspiron 3050.

2024-05-27platform/x86: touchscreen_dmi: Add support for setting touchscreen ↵Hans de Goede
properties from cmdline On x86/ACPI platforms touchscreens mostly just work without needing any device/model specific configuration. But in some cases (mostly with Silead and Goodix touchscreens) it is still necessary to manually specify various touchscreen-properties on a per model basis. touchscreen_dmi is a special place for DMI quirks for this, but it can be challenging for users to figure out the right property values, especially for Silead touchscreens where non of these can be read back from the touchscreen-controller. ATM users can only test touchscreen properties by editing touchscreen_dmi.c and then building a completely new kernel which makes it unnecessary difficult for users to test and submit properties when necessary for their laptop / tablet model. Add support for specifying properties on the kernel commandline to allow users to easily figure out the right settings. See the added documentation in kernel-parameters.txt for the commandline syntax.

2024-05-15platform/x86: Add new MeeGoPad ANX7428 Type-C Cross Switch driverHans de Goede
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.

2024-05-14platform/x86: Add new Dell UART backlight driverHans de Goede
Dell All In One (AIO) models released after 2017 use a backlight controller board connected to an UART. In DSDT this uart port will be defined as: Name (_HID, "DELL0501") Name (_CID, EisaId ("PNP0501") Instead of having a separate ACPI device with an UartSerialBusV2() resource to model the backlight-controller, which would be the standard way to do this. The acpi_quirk_skip_serdev_enumeration() has special handling for this and it will make the serial port code create a serdev controller device for the UART instead of a /dev/ttyS0 char-dev. It will also create a dell-uart-backlight driver platform device for this driver to bind too. This new kernel module contains 2 drivers for this: 1. A simple platform driver which creates the actual serdev device (with the serdev controller device as parent) 2. A serdev driver for the created serdev device which exports the backlight functionality uses a standard backlight class device.

2024-05-14platform/x86: x86-android-tablets: Create LED device for Xiaomi Pad 2 bottom ↵Hans de Goede
bezel touch buttons The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED controller which is controlled by the "pwm_soc_lpss_2" PWM output. Create a LED class device for this, using the new input-events trigger as default trigger so that the buttons automatically light up on any input activity. Note alternatively a "leds_pwm" platform device could be created together with the necessary fwnode_s_ and a fwnode link to the PWM controller. There are 2 downsides to this approach: 1. The code would still need to pwm_get() the PWM controller to get/attach a fwnode for the PWM controller fwnode link and setting up the necessary fwnodes is non-trivial. So this would likely require more code then simply registering the LED class device directly. 2. Currently the leds_pwm driver and its devicetree bindings do not support limiting the maximum dutycycle to less then 100% which is required in this case (the leds_pwm driver can probably be extended to allow this).

2024-04-29platform/x86: ISST: Support partitioned systemsSrinivas Pandruvada
A partitioned system has two different PCI VSEC devices per package. A non-partitioned device has only one PCI VSEC device per package. The current implementation only supports non partitioned systems. Each partition maps a set of power domains. Other than reading from different MMIO regions, there is no change in the SST functionality. The scope of SST control is still per power domain. Hence user space does not need to be aware of existence of partitions. With partitions, existing per package information defined using struct tpmi_sst_struct is enhanced to store information for both partitions. A mapping function map_partition_power_domain_id() is introduced, which maps to correct partition and index. This mapping function is called in get_instance() and isst_if_clos_assoc(), before indexing into tpmi_sst_struct->power_domain_info[]. The TPMI core platform info provides partition id and compute die ID mask for each partition. Use this information to order power domains, so that compute dies are presented before IO dies to match hardware defined compute die ID for each CPU.

2024-04-29platform/x86: ISST: Shorten the assignments for power_domain_infoSrinivas Pandruvada
Instead of long lines for assignment to tpmi_sst->power_domain_info, use a local variable pd_info and assign later. Also move the assignment of number of resources after the assignment of pd_info. No functional change is expected.

2024-04-29platform/x86/intel/tpmi: Add additional TPMI header fieldsSrinivas Pandruvada
TPMI information header added additional fields in version 2. Some of the reserved fields in version 1 are used to define new fields. Parse new fields and export as part of platform data. These fields include: - PCI segment ID - Partition ID of the package: If a package is represented by more than one PCI device, then partition ID along with cdie_mask, describes the scope. For example to update get/set properties for a compute die, one of the PCI MMIO region is selected from the partition ID. - cdie_mask: Mask of all compute dies in this partition.
