From: Simon Shields simon@lineageos.org

This patch adds support for voice and BT calls, along with standard audio output via the speaker, earpiece, headphone jack, HDMI, and any accessories compatible with Midas boards. This patch also supports headphone/headset detection and headsets with inline buttons.
