+Analog Devices ADV7511(W)/13/33/35 HDMI Encoders
+------------------------------------------------
+
+The ADV7511, ADV7511W, ADV7513, ADV7533 and ADV7535 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. ADV7533/5 supports the DSI interface for input
+pixels, while the others support RGB interface.
+
+Required properties:
+
+- compatible: Should be one of:
+		"adi,adv7511"
+		"adi,adv7511w"
+		"adi,adv7513"
+		"adi,adv7533"
+		"adi,adv7535"
+
+- reg: I2C slave addresses
+  The ADV7511 internal registers are split into four pages exposed through
+  different I2C addresses, creating four register maps. Each map has it own
+  I2C address and acts as a standard slave device on the I2C bus. The main
+  address is mandatory, others are optional and revert to defaults if not
+  specified.
+
+
+The ADV7511 supports a large number of input data formats that differ by their
+color depth, color format, clock mode, bit justification and random
+arrangement of components on the data bus. The combination of the following
+properties describe the input and map directly to the video input tables of the
+ADV7511 datasheet that document all the supported combinations.
+
+- adi,input-depth: Number of bits per color component at the input (8, 10 or
+  12).
+- adi,input-colorspace: The input color space, one of "rgb", "yuv422" or
+  "yuv444".
+- adi,input-clock: The input clock type, one of "1x" (one clock cycle per
+  pixel), "2x" (two clock cycles per pixel), "ddr" (one clock cycle per pixel,
+  data driven on both edges).
+
+The following input format properties are required except in "rgb 1x" and
+"yuv444 1x" modes, in which case they must not be specified.
+
+- adi,input-style: The input components arrangement variant (1, 2 or 3), as
+  listed in the input format tables in the datasheet.
+- adi,input-justification: The input bit justification ("left", "evenly",
+  "right").
+
+- avdd-supply: A 1.8V supply that powers up the AVDD pin on the chip.
+- dvdd-supply: A 1.8V supply that powers up the DVDD pin on the chip.
+- pvdd-supply: A 1.8V supply that powers up the PVDD pin on the chip.
+- dvdd-3v-supply: A 3.3V supply that powers up the pin called DVDD_3V
+  on the chip.
+- bgvdd-supply: A 1.8V supply that powers up the BGVDD pin. This is
+  needed only for ADV7511.
+
+The following properties are required for ADV7533 and ADV7535:
+
+- adi,dsi-lanes: Number of DSI data lanes connected to the DSI host. It should
+  be one of 1, 2, 3 or 4.
+- a2vdd-supply: 1.8V supply that powers up the A2VDD pin on the chip.
+- v3p3-supply: A 3.3V supply that powers up the V3P3 pin on the chip.
+- v1p2-supply: A supply that powers up the V1P2 pin on the chip. It can be
+  either 1.2V or 1.8V for ADV7533 but only 1.8V for ADV7535.
+
+Optional properties:
+
+- interrupts: Specifier for the ADV7511 interrupt
+- pd-gpios: Specifier for the GPIO connected to the power down signal
+
+- adi,clock-delay: Video data clock delay relative to the pixel clock, in ps
+  (-1200 ps .. 1600 ps). Defaults to no delay.
+- 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 and ADV7535. 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.
+- clocks: from common clock binding: reference to the CEC clock.
+- clock-names: from common clock binding: must be "cec".
+- reg-names : Names of maps with programmable addresses.
+	It can contain any map needing a non-default address.
+	Possible maps names are : "main", "edid", "cec", "packet"
+
+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, YUV or DSI input. In the case of ADV7533/5, the
+  remote endpoint phandle should be a reference to a valid mipi_dsi_host device
+  node.
+- Video port 1 for the HDMI output
+- Audio port 2 for the HDMI audio input
+
