Subject: [PATCH v2 3/3] arm64: dts: qcom: sdm845-oneplus: add tri-state-key
Date: Fri, 10 Feb 2023 00:25:56 +0100	[thread overview]
Message-ID: <20230209232556.91554-1-soyer@irl.hu> (raw)

The tri-state-key is a sound profile switch found on the OnePlus 6,
Android maps the states to "mute", "vibrate" and "ring". Expose them as
ABS_SND_PROFILE events.
The previous GPIO numbers were wrong. Update them to the correct
ones.
