[PATCH 0/2] Add support for the new phone link hotkey on ThinkPads

[Illia Ostapyshyn]

The Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s Gen 5 laptops feature a new
hotkey on F11 showing a smartphone and a laptop chained together.  According to
the user manual [1], it launches the Microsoft Phone Link software used to
connect to Android/iOS devices and relay messages/calls or sync data.

This new keycode can be interpreted by desktop environments to lauch free Phone
Link alternatives like KDE Connect or GSConnect.

[PATCH 1/2] Input: allocate keycode for phone linking

[Illia Ostapyshyn]

The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s
Gen 5 laptops includes a symbol showing a smartphone and a laptop
chained together.  According to the user manual, it starts the Microsoft
Phone Link software used to connect to Android/iOS devices and relay
messages/calls or sync data.

As there are no suitable keycodes for this action, introduce a new one.

[PATCH 2/2] platform/x86: thinkpad_acpi: Add support for new phone link hotkey

[Illia Ostapyshyn]

The F11 key on the new Lenovo Thinkpad T14 Gen 5, T16 Gen 3, and P14s
Gen 5 laptops includes a symbol showing a smartphone and a laptop
chained together.  According to the user manual, it starts the Microsoft
Phone Link software used to connect to Android/iOS devices and relay
messages/calls or sync data.

These laptops send the 0x1320 hkey event when the key is pressed.  Map
this event to the new KEY_LINK_PHONE keycode.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
