1 Analog Device ADV7511(W)/13/33/35 HDMI Encoders
2 -----------------------------------------
4 The ADV7511, ADV7511W, ADV7513, ADV7533 and ADV7535 are HDMI audio and video
5 transmitters compatible with HDMI 1.4 and DVI 1.0. They support color space
6 conversion, S/PDIF, CEC and HDCP. ADV7533/5 supports the DSI interface for input
7 pixels, while the others support RGB interface.
11 - compatible: Should be one of:
18 - reg: I2C slave addresses
19 The ADV7511 internal registers are split into four pages exposed through
20 different I2C addresses, creating four register maps. Each map has it own
21 I2C address and acts as a standard slave device on the I2C bus. The main
22 address is mandatory, others are optional and revert to defaults if not
26 The ADV7511 supports a large number of input data formats that differ by their
27 color depth, color format, clock mode, bit justification and random
28 arrangement of components on the data bus. The combination of the following
29 properties describe the input and map directly to the video input tables of the
30 ADV7511 datasheet that document all the supported combinations.
32 - adi,input-depth: Number of bits per color component at the input (8, 10 or
34 - adi,input-colorspace: The input color space, one of "rgb", "yuv422" or
36 - adi,input-clock: The input clock type, one of "1x" (one clock cycle per
37 pixel), "2x" (two clock cycles per pixel), "ddr" (one clock cycle per pixel,
38 data driven on both edges).
40 The following input format properties are required except in "rgb 1x" and
41 "yuv444 1x" modes, in which case they must not be specified.
43 - adi,input-style: The input components arrangement variant (1, 2 or 3), as
44 listed in the input format tables in the datasheet.
45 - adi,input-justification: The input bit justification ("left", "evenly",
48 - avdd-supply: A 1.8V supply that powers up the AVDD pin on the chip.
49 - dvdd-supply: A 1.8V supply that powers up the DVDD pin on the chip.
50 - pvdd-supply: A 1.8V supply that powers up the PVDD pin on the chip.
51 - dvdd-3v-supply: A 3.3V supply that powers up the pin called DVDD_3V
53 - bgvdd-supply: A 1.8V supply that powers up the BGVDD pin. This is
54 needed only for ADV7511.
56 The following properties are required for ADV7533 and ADV7535:
58 - adi,dsi-lanes: Number of DSI data lanes connected to the DSI host. It should
59 be one of 1, 2, 3 or 4.
60 - a2vdd-supply: 1.8V supply that powers up the A2VDD pin on the chip.
61 - v3p3-supply: A 3.3V supply that powers up the V3P3 pin on the chip.
62 - v1p2-supply: A supply that powers up the V1P2 pin on the chip. It can be
63 either 1.2V or 1.8V for ADV7533 but only 1.8V for ADV7535.
67 - interrupts: Specifier for the ADV7511 interrupt
68 - pd-gpios: Specifier for the GPIO connected to the power down signal
70 - adi,clock-delay: Video data clock delay relative to the pixel clock, in ps
71 (-1200 ps .. 1600 ps). Defaults to no delay.
72 - adi,embedded-sync: The input uses synchronization signals embedded in the
73 data stream (similar to BT.656). Defaults to separate H/V synchronization
75 - adi,disable-timing-generator: Only for ADV7533 and ADV7535. Disables the
76 internal timing generator. The chip will rely on the sync signals in the
77 DSI data lanes, rather than generate its own timings for HDMI output.
78 - clocks: from common clock binding: reference to the CEC clock.
79 - clock-names: from common clock binding: must be "cec".
80 - reg-names : Names of maps with programmable addresses.
81 It can contain any map needing a non-default address.
82 Possible maps names are : "main", "edid", "cec", "packet"
86 The ADV7511 has two video ports. Their connections are modelled using the OF
87 graph bindings specified in Documentation/devicetree/bindings/graph.txt.
89 - Video port 0 for the RGB, YUV or DSI input. In the case of ADV7533/5, the
90 remote endpoint phandle should be a reference to a valid mipi_dsi_host device
92 - Video port 1 for the HDMI output
93 - Audio port 2 for the HDMI audio input
