Subject: [PATCH 1/6] ASoC: dt-bindings: midas-audio: Declare required
 properties for GPIO jack det

GPIO jack detection requires an IIO channel and the detection threshold
to work. Explicitly declare the requirement in DT schema.

Fixes: 0a590ecc672a ("ASoC: dt-bindings: samsung,midas-audio: Add GPIO-based headset jack detection")
