HID: intel-thc-hid: Set HID_PHYS with PCI BDF

2026-03-16T10:25:07Z

Currently HID_PHYS is empty, which means userspace tools (e.g. fwupd) that depend on it for distinguishing the devices, are unable to do so. Other drivers like i2c-hid, usbhid, surface-hid, all populate it. With this change it's set to, for example: HID_PHYS=0000:00:10.0 Each function has just a single HID device, as far as I can tell, so there is no need to add a suffix. Tested with fwupd 2.1.1, can avoid https://github.com/fwupd/fwupd/pull/9995 Cc: Even Xu Cc: Xinpeng Sun Cc: Jiri Kosina Cc: Benjamin Tissoires Cc: Sakari Ailus Signed-off-by: Daniel Schaefer Reviewed-by: Even Xu Signed-off-by: Jiri Kosina

HID: Intel-thc-hid: Intel-quicki2c: Add output report support

2026-01-07T21:03:47Z

Add support for HID output reports in the intel-quicki2c driver by implementing the output_report callback in the HID low-level driver interface. This enables proper communication with HID devices that require output report functionality, such as setting device configuration or updating device firmware.

HID: intel-thc-hid: Remove redundant pm_runtime_mark_last_busy() calls

2025-10-30T10:27:17Z

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy(). Signed-off-by: Sakari Ailus Reviewed-by: Even Xu Signed-off-by: Jiri Kosina

HID: intel-thc-hid: intel-quicki2c: Add HIDI2C protocol implementation

2025-01-09T09:14:16Z

Intel QuickI2C driver uses THC hardware to accelerate HID over I2C (HIDI2C) protocol flow. This patch implements all data flows described in HID over I2C protocol SPEC by using THC hardware layer APIs.
