-Analog Device ADV7511(W)/13/33 HDMI Encoders
------------------------------------------
-
-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. 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"
- "adi,adv7513"
- "adi,adv7533"
-
-- 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:
-
-- 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.
-
-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. 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, 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
