Subject: [PATCH 1/3] input: add event codes for user programmable switch events
Message-ID: <20220516142158.1612109-1-caleb@connolly.tech>

Add SW_PROG{1,2,3,4} for device switches which are handled by userspace.

This can be used for devices with "generic" switches which are intended
to be user-programmable, for example OnePlus phones contain a tri-state
key which can be used for switching between mute/vibrate/ring, or
programmed by the user to perform any arbitrary actions.

These are analogous to the keys KEY_PROG{1,2,3,4} found on some
keyboards.
