+ps8640-bridge bindings
+
+Required properties:
+       - compatible: "parade,ps8640"
+       - reg: first i2c address of the bridge
+       - power-gpios: OF device-tree gpio specification for power pin.
+       - reset-gpios: OF device-tree gpio specification for reset pin.
+       - mode-sel-gpios: OF device-tree gpio specification for mode-sel pin.
+       - ps8640-1v2-supply: OF device-tree regulator specification for 1v2.
+       - ps8640-3v3-supply: OF device-tree regulator specification for 3v3.
+
+Optional properties:
+       - video interfaces: Device node can contain video interface port
+                           nodes for panel according to [1].
