2024-04-15platform/x86: ideapad-laptop: add FnLock LED class deviceGergo Koteles

2024-04-11platform/chrome: cros_ec_uart: properly fix race conditionNoah Loomans
The cros_ec_uart_probe() function calls devm_serdev_device_open() before it calls serdev_device_set_client_ops(). This can trigger a NULL pointer dereference: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... Call Trace: <TASK> ... ? ttyport_receive_buf A simplified version of crashing code is as follows: static inline size_t serdev_controller_receive_buf(struct serdev_controller *ctrl, const u8 *data, size_t count) { struct serdev_device *serdev = ctrl->serdev; if (!serdev || !serdev->ops->receive_buf) // CRASH! return 0; return serdev->ops->receive_buf(serdev, data, count); } It assumes that if SERPORT_ACTIVE is set and serdev exists, serdev->ops will also exist. This conflicts with the existing cros_ec_uart_probe() logic, as it first calls devm_serdev_device_open() (which sets SERPORT_ACTIVE), and only later sets serdev->ops via serdev_device_set_client_ops(). Commit 01f95d42b8f4 ("platform/chrome: cros_ec_uart: fix race condition") attempted to fix a similar race condition, but while doing so, made the window of error for this race condition to happen much wider. Attempt to fix the race condition again, making sure we fully setup before calling devm_serdev_device_open().

2024-04-08platform/x86: asus-wmi: ROG Ally increase wait time, allow MCU powersaveLuke D. Jones
The previous work to allow the MCU to be resumed correctly after sleep and resume tried to take the shortest possible time. However as work continues in various other parts of the s2idle subsystems it has shown that it wasn't entirely reliable. If the MCU disable/enable call is done correctly the MCU fully removes its USB endpoints, and this shows as a full USB device reconnection on resume. When we tried to short this as much as possible sometimes the MCU doesn't get to complete what it needs to do before going to low-power and this affected the reconnection. Through trial it is found that the minimum time required is approx 1200ms to allow a proper disconnect and disable, and the same amount of time on resume is required to prevent a rapid disconnect/reconnect happening on seemingly random occasions. To be safe the time is now 1500ms for msleep. Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Luke D.

This patch adds storing of those values in the local struct, and enables reading of those values back. To prevent creating a series of byte holes in the struct the "<name>_available" bool is removed and `asus_sysfs_is_visible()` uses the `ASUS_WMI_DEVID_<name>` directly.

2024-04-08platform/x86: intel-vbtn: Update tablet mode switch at end of probeGwendal Grignou
ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as follow: Device (VGBI) { Name (_HID, EisaId ("INT33D6") ... Name (VBDS, Zero) Method (_STA, 0, Serialized) // _STA: Status ... Method (VBDL, 0, Serialized) { PB1E |= 0x20 VBDS |= 0x40 } Method (VGBS, 0, Serialized) { Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */ } ... } By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set) only after method VBDL is executed. Since VBDL is now evaluated in the probe routine later, after the device is registered, the retrieved value of VBDS was still 0 ("tablet mode") when setting up the virtual switch. Make sure to evaluate VGBS after VBDL, to ensure the convertible boots in clamshell mode, the expected default.

2024-04-08platform/x86/amd/hsmp: switch to use device_add_groups()Greg Kroah-Hartman
devm_device_add_groups() is being removed from the kernel, so move the hsmp driver to use device_add_groups() instead. The logic is identical, when the device is removed the driver core will properly clean up and remove the groups, and the memory used by the attribute groups will be freed because it was created with dev_* calls, so this is functionally identical overall.

2024-04-08platform/x86: toshiba_acpi: Add quirk for buttons on Z830Arvid Norlander
The Z830 has some buttons that will only work properly as "quickstart" buttons. To enable them in that mode, a value between 1 and 7 must be used for HCI_HOTKEY_EVENT. Windows uses 0x5 on this laptop so use that for maximum predictability and compatibility. As there is not yet a known way of auto detection, this patch uses a DMI quirk table. A module parameter is exposed to allow setting this on other models for testing.

2024-04-08platform/x86: Add ACPI quickstart button (PNP0C32) driverArmin Wolf
This drivers supports the ACPI quickstart button device, which is used to send manufacturer-specific events to userspace. Since the meaning of those events is not standardized, userspace has to use for example hwdb to decode them. The driver itself is based on an earlier proposal, but contains some improvements and uses the device wakeup API instead of a custom sysfs file.

There is a KTD2026 LED controller to manage the indicator LED for Xiaomi pad2. The ACPI for it is not properly made so the kernel can't get a correct description of it. This work adds a description for this RGB LED controller and also sets a trigger to indicate the charging event (bq27520-0-charging). When it is charging, the indicator LED will be turned on.

2024-03-25platform/x86: wmi: Avoid returning AE_OK upon unknown errorArmin Wolf
If an error code other than EINVAL, ENODEV or ETIME is returned by ec_read()/ec_write(), then AE_OK is wrongly returned. Fix this by only returning AE_OK if the return code is 0, and return AE_ERROR otherwise. Tested on a Dell Inspiron 3505 and a Asus Prime B650-Plus.

2024-03-25platform: arm64: Add Acer Aspire 1 embedded controller driverNikita Travkin
Acer Aspire 1 is a Snapdragon 7c based laptop. It uses an embedded controller to perform a set of various functions, such as: - Battery and charger monitoring; - Keyboard layout control (i.e. fn_lock settings); - USB Type-C DP alt mode HPD notifications; - Laptop lid status. Unfortunately, while all this functionality is implemented in ACPI, it's currently not possible to use ACPI to boot Linux on such Qualcomm devices. To allow Linux to still support the features provided by EC, this driver reimplments the relevant ACPI parts. This allows us to boot the laptop with Device Tree and retain all the features.
