[PATCH] Input: SoC button array: add mapping for airplane mode button

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christoffer Sandberg <cs@xxxxxxxxx>

This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.

While it is physically a key it behaves more like a switch, sending a key
down on first press and a key up on 2nd press. Therefor the switch event is
used here. Besides this behaviour it uses the HID usage-id 0xc6 (Wireless
Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but since
neither 0xc6 nor 0xc8 are currently implemented at all in soc_button_array
this not to standard behaviour is not put behind a quirk for the moment.
