The Allwinner A10 Display pipeline is composed of several components
that are going to be documented below:
+For the input port of all components up to the TCON in the display
+pipeline, if there are multiple components, the local endpoint IDs
+must correspond to the index of the upstream block. For example, if
+the remote endpoint is Frontend 1, then the local endpoint ID must
+be 1.
+
+Conversely, for the output ports of the same group, the remote endpoint
+ID must be the index of the local hardware block. If the local backend
+is backend 1, then the remote endpoint ID must be 1.
+
+HDMI Encoder
+------------
+
+The HDMI Encoder supports the HDMI video and audio outputs, and does
+CEC. It is one end of the pipeline.
+
+Required properties:
+ - compatible: value must be one of:
+ * allwinner,sun5i-a10s-hdmi
+ - reg: base address and size of memory-mapped region
+ - interrupts: interrupt associated to this IP
+ - clocks: phandles to the clocks feeding the HDMI encoder
+ * ahb: the HDMI interface clock
+ * mod: the HDMI module clock
+ * pll-0: the first video PLL
+ * pll-1: the second video PLL
+ - clock-names: the clock names mentioned above
+ - dmas: phandles to the DMA channels used by the HDMI encoder
+ * ddc-tx: The channel for DDC transmission
+ * ddc-rx: The channel for DDC reception
+ * audio-tx: The channel used for audio transmission
+ - dma-names: the channel names mentioned above
+
+ - 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. The second should be the
+ output, usually to an HDMI connector.
