Input: add keycodes for contextual AI usages (HUTRR119)

2026-03-29T20:02:11Z

HUTRR119 introduces new usages for keys intended to invoke AI agents based on the current context. These are useful with the increasing number of operating systems with integrated Large Language Models Add new key definitions for KEY_ACTION_ON_SELECTION, KEY_CONTEXTUAL_INSERT and KEY_CONTEXTUAL_QUERY Signed-off-by: Akshai Murari Acked-by: Dmitry Torokhov Signed-off-by: Jiri Kosina

HID: input: Add support for multiple batteries per device

2026-03-19T14:52:45Z

Add support for HID devices that report multiple batteries, each identified by its report ID. The hid_device->battery pointer is replaced with a batteries list. Batteries are named using the pattern hid-{uniq}-battery-{report_id}. The hid_get_battery() helper returns the first battery in the list for backwards compatibility with single-battery drivers.

HID: input: Introduce struct hid_battery and refactor battery code

2026-03-19T14:52:45Z

Introduce struct hid_battery to encapsulate individual battery state, preparing for future multi-battery support. The new structure contains all battery-related fields previously stored directly in hid_device (capacity, min, max, report_type, report_id, charge_status, etc.). The hid_device->battery pointer type changes from struct power_supply* to struct hid_battery*, and all battery functions are refactored accordingly. A hid_get_battery() helper is added for external drivers, with hid-apple.c and hid-magicmouse.c updated to use the new API. The hid-input-test.c KUnit tests are also updated for the new structure. No functional changes for single-battery devices. Signed-off-by: Lucas Zampieri Signed-off-by: Benjamin Tissoires

HID: input: Convert battery code to devm_*

2026-03-19T14:52:45Z

Convert the HID battery code to use devm_* managed resource APIs for the power_supply_desc allocation, battery name string, and power supply registration. The error path uses devm_kfree() to clean up allocated memory if devm_power_supply_register() fails, preventing memory waste on repeated setup attempts. The hidinput_cleanup_battery() function is removed as devm handles cleanup automatically. Signed-off-by: Lucas Zampieri Signed-off-by: Benjamin Tissoires

HID: input: use __free(kfree) to clean up temporary buffers

2026-03-19T14:45:15Z

The __free() cleanup automatically releases given resource when leaving the scope, so use it to make the code less cluttered with error handling. Signed-off-by: Dmitry Torokhov Signed-off-by: Jiri Kosina

HID: input: Add HID_BATTERY_QUIRK_DYNAMIC for Elan touchscreens

2026-03-11T14:26:47Z

Elan touchscreens have a HID-battery device for the stylus which is always there even if there is no stylus. This is causing upower to report an empty battery for the stylus and some desktop-environments will show a notification about this, which is quite annoying. Because of this the HID-battery is being ignored on all Elan I2c and USB touchscreens, but this causes there to be no battery reporting for the stylus at all. This adds a new HID_BATTERY_QUIRK_DYNAMIC and uses these for the Elan touchscreens. This new quirks causes the present value of the battery to start at 0, which will make userspace ignore it and only sets present to 1 after receiving a battery input report which only happens when the stylus gets in range.
