Analog Device ADV7511(W)/13/33 HDMI Encoders
-----------------------------------------
The ADV7511, ADV7511W and ADV7513 are HDMI audio and video transmitters
The ADV7511, ADV7511W, ADV7513 and ADV7533 are HDMI audio and video transmitters
compatible with HDMI 1.4 and DVI 1.0. They support color space conversion,
S/PDIF, CEC and HDCP.
S/PDIF, CEC and HDCP. ADV7533 supports the DSI interface for input pixels, while
the others support RGB interface.
Required properties:
- compatible: Should be one of "adi,adv7511", "adi,adv7511w" or "adi,adv7513"
- compatible: Should be one of:
"adi,adv7511"
"adi,adv7511w"
"adi,adv7513"
"adi,adv7533"

The following properties are required for ADV7533:
- adi,dsi-lanes: Number of DSI data lanes connected to the DSI host. It should
be one of 1, 2, 3 or 4.

- adi,embedded-sync: The input uses synchronization signals embedded in the
data stream (similar to BT.656). Defaults to separate H/V synchronization
signals.
- adi,disable-timing-generator: Only for ADV7533. Disables the internal timing
generator. The chip will rely on the sync signals in the DSI data lanes,
rather than generate its own timings for HDMI output.
Required nodes:
The ADV7511 has two video ports. Their connections are modelled using the OF
graph bindings specified in Documentation/devicetree/bindings/graph.txt.
- Video port 0 for the RGB or YUV input
- Video port 0 for the RGB, YUV or DSI input. In the case of ADV7533, the
remote endpoint phandle should be a reference to a valid mipi_dsi_host device
node.
- Video port 1 for the HDMI output
