1 Analog Device ADV7511(W)/13/33 HDMI Encoders
2 -----------------------------------------
4 The ADV7511, ADV7511W, ADV7513 and ADV7533 are HDMI audio and video transmitters
5 compatible with HDMI 1.4 and DVI 1.0. They support color space conversion,
6 S/PDIF, CEC and HDCP. ADV7533 supports the DSI interface for input pixels, while
7 the others support RGB interface.
11 - compatible: Should be one of:
17 - reg: I2C slave address
19 The ADV7511 supports a large number of input data formats that differ by their
20 color depth, color format, clock mode, bit justification and random
21 arrangement of components on the data bus. The combination of the following
22 properties describe the input and map directly to the video input tables of the
23 ADV7511 datasheet that document all the supported combinations.
25 - adi,input-depth: Number of bits per color component at the input (8, 10 or
27 - adi,input-colorspace: The input color space, one of "rgb", "yuv422" or
29 - adi,input-clock: The input clock type, one of "1x" (one clock cycle per
30 pixel), "2x" (two clock cycles per pixel), "ddr" (one clock cycle per pixel,
31 data driven on both edges).
33 The following input format properties are required except in "rgb 1x" and
34 "yuv444 1x" modes, in which case they must not be specified.
36 - adi,input-style: The input components arrangement variant (1, 2 or 3), as
37 listed in the input format tables in the datasheet.
38 - adi,input-justification: The input bit justification ("left", "evenly",
41 - avdd-supply: A 1.8V supply that powers up the AVDD pin on the chip.
42 - dvdd-supply: A 1.8V supply that powers up the DVDD pin on the chip.
43 - pvdd-supply: A 1.8V supply that powers up the PVDD pin on the chip.
44 - dvdd-3v-supply: A 3.3V supply that powers up the pin called DVDD_3V
46 - bgvdd-supply: A 1.8V supply that powers up the BGVDD pin. This is
47 needed only for ADV7511.
49 The following properties are required for ADV7533:
51 - adi,dsi-lanes: Number of DSI data lanes connected to the DSI host. It should
52 be one of 1, 2, 3 or 4.
53 - a2vdd-supply: 1.8V supply that powers up the A2VDD pin on the chip.
54 - v3p3-supply: A 3.3V supply that powers up the V3P3 pin on the chip.
55 - v1p2-supply: A supply that powers up the V1P2 pin on the chip. It can be
60 - interrupts: Specifier for the ADV7511 interrupt
61 - pd-gpios: Specifier for the GPIO connected to the power down signal
63 - adi,clock-delay: Video data clock delay relative to the pixel clock, in ps
64 (-1200 ps .. 1600 ps). Defaults to no delay.
65 - adi,embedded-sync: The input uses synchronization signals embedded in the
66 data stream (similar to BT.656). Defaults to separate H/V synchronization
68 - adi,disable-timing-generator: Only for ADV7533. Disables the internal timing
69 generator. The chip will rely on the sync signals in the DSI data lanes,
70 rather than generate its own timings for HDMI output.
71 - clocks: from common clock binding: reference to the CEC clock.
72 - clock-names: from common clock binding: must be "cec".
76 The ADV7511 has two video ports. Their connections are modelled using the OF
77 graph bindings specified in Documentation/devicetree/bindings/graph.txt.
79 - Video port 0 for the RGB, YUV or DSI input. In the case of ADV7533, the
80 remote endpoint phandle should be a reference to a valid mipi_dsi_host device
82 - Video port 1 for the HDMI output
83 - Audio port 2 for the HDMI audio input
