   3 Required properties:
   4 - compatible: "rockchip,rk3288-hdmi-analog"
   5 - rockchip,model: The user-visible name of this sound complex
   6 - rockchip,i2s-controller: The phandle of the Rockchip I2S controller that's
   7   connected to the CODEC
   8 - rockchip,audio-codec: The phandle of the analog audio codec.
   9 - rockchip,routing: A list of the connections between audio components.
  10                     Each entry is a pair of strings, the first being the
  11                     connection's sink, the second being the connection's
