Subject: [PATCH v2] HID: input: Add support for Programmable Buttons
Date: Wed, 19 May 2021 19:43:45 +0200 [thread overview]
Message-ID: <20210519174345.614467-1-linux@weissschuh.net> (raw)
In-Reply-To: <2dc197eb-a222-8af6-f0ab-f722e4f492ca@redhat.com>
Map them to KEY_MACRO# event codes.
These buttons are defined by HID as follows:
"The user defines the function of these buttons to control software applications or GUI objects."
This matches the semantics of the KEY_MACRO# input event codes that Linux supports.
