From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> This patch add new bindings required to support MBHC (Multi Button Headset Control) block in the codec. This block is used for jack insert/removal detection, headset type detection and 8 button press/release events. All these properties are very much specific to board.
