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-thc: Fix wrong register fields updating

2026-02-02T13:39:30Z

Clear the target bit fields in register before setting new values. This ensures proper field updates by removing any existing bits that might interfere with the new configuration.

HID: Intel-thc-hid: Intel-quicki2c: Add power management for touch device

2026-01-07T21:04:37Z

Send POWER_SLEEP command to touch device when system enters into sleep mode or hibernate mode to save more power; and send POWER_ON command to take device back when system exits sleep mode. Signed-off-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: Intel-quicki2c: Support writing output report format

2026-01-07T21:03:47Z

There are two output formats requested in the HID-over-I2C specification: - Command format (set feature/set report): encoded command written to command register, followed by data written to data register - Output report format: all data written directly to output register Current quicki2c_init_write_buf() implementation only supports the command format. Extend quicki2c_init_write_buf() to automatically detect the output format based on the presence of command parameters and prepare the appropriate output buffer accordingly.

HID: Intel-thc-hid: Intel-quicki2c: Use put_unaligned_le16 for __le16 writes

2026-01-07T21:03:47Z

Replace memcpy operations with put_unaligned_le16() when writing 16-bit little-endian values to the write buffer. This change improves code clarity and ensures proper handling of unaligned memory access. Signed-off-by: Even Xu Signed-off-by: Jiri Kosina

HID: Intel-thc-hid: Intel-quicki2c: Use size_t for all length variables

2026-01-07T21:03:47Z

Convert all length-related variables in the QuickI2C protocol layer to use size_t type to follow kernel coding conventions. This includes: - All buffer length parameters and variables - Return values of quicki2c_encode_cmd() function which represents encoded command buffer size. - Return values of quicki2c_init_write_buf() function which represents process result: either prepared output buffer size or error code. This change improves type consistency and aligns with standard kernel practices for memory size representation, reducing potential issues with size calculations and comparisons.
