Allwinner A31 DSI Encoder
=========================

The DSI pipeline consists of two separate blocks: the DSI controller
itself, and its associated D-PHY.

DSI Encoder
-----------

The DSI Encoder generates the DSI signal from the TCON's.

Required properties:
  - compatible: value must be one of:
    * allwinner,sun6i-a31-mipi-dsi
  - reg: base address and size of memory-mapped region
  - interrupts: interrupt associated to this IP
  - clocks: phandles to the clocks feeding the DSI encoder
    * bus: the DSI interface clock
    * mod: the DSI module clock
  - clock-names: the clock names mentioned above
  - phys: phandle to the D-PHY
  - phy-names: must be "dphy"
  - resets: phandle to the reset controller driving the encoder

  - ports: A ports node with endpoint definitions as defined in
    Documentation/devicetree/bindings/media/video-interfaces.txt. The
    first port should be the input endpoint, usually coming from the
    associated TCON.

Any MIPI-DSI device attached to this should be described according to
the bindings defined in ../mipi-dsi-bus.txt

D-PHY
-----

Required properties:
  - compatible: value must be one of:
    * allwinner,sun6i-a31-mipi-dphy
  - reg: base address and size of memory-mapped region
  - clocks: phandles to the clocks feeding the DSI encoder
    * bus: the DSI interface clock
    * mod: the DSI module clock
  - clock-names: the clock names mentioned above
  - resets: phandle to the reset controller driving the encoder

	};
};
