* Analog Devices ADV748X video decoder with HDMI receiver
The ADV7481 and ADV7482 are multi format video decoders with an integrated
HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
from three input sources HDMI, analog and TTL.
Required Properties:
- compatible: Must contain one of the following
- "adi,adv7481" for the ADV7481
- "adi,adv7482" for the ADV7482
- reg: I2C slave addresses
The ADV748x has up to twelve 256-byte maps that can be accessed via the
main I2C ports. 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 remain at default values if not specified.
Optional Properties:
- interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
"intrq3". All interrupts are optional. The "intrq3" interrupt
is only available on the adv7481
- interrupts: Specify the interrupt lines for the ADV748x
- reg-names : Names of maps with programmable addresses.
It shall contain all maps needing a non-default address.
Possible map names are:
"main", "dpll", "cp", "hdmi", "edid", "repeater",
"infoframe", "cbus", "cec", "sdp", "txa", "txb"
The device node must contain one 'port' child node per device input and output
port, in accordance with the video interface bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt. The port nodes
are numbered as follows.
Name Type Port
---------------------------------------
AIN0 sink 0
AIN1 sink 1
AIN2 sink 2
AIN3 sink 3
AIN4 sink 4
AIN5 sink 5
AIN6 sink 6
AIN7 sink 7
HDMI sink 8
TTL sink 9
TXA source 10
TXB source 11
The digital output port nodes, when present, shall contain at least one
endpoint. Each of those endpoints shall contain the data-lanes property as
described in video-interfaces.txt.
Required source endpoint properties:
- data-lanes: an array of physical data lane indexes
The accepted value(s) for this property depends on which of the two
sources are described. For TXA 1, 2 or 4 data lanes can be described
while for TXB only 1 data lane is valid. See video-interfaces.txt
for detailed description.
Ports are optional if they are not connected to anything at the hardware level.
Example:
video-receiver@70 {
compatible = "adi,adv7482";

buffers are out-of-order compared to the ``OUTPUT`` buffers): ``CAPTURE``
timestamps will not retain the order of ``OUTPUT`` timestamps.
.. note::
The backing memory of ``CAPTURE`` buffers that are used as reference frames
by the stream may be read by the hardware even after they are dequeued.
Consequently, the client should avoid writing into this memory while the
``CAPTURE`` queue is streaming. Failure to observe this may result in
corruption of decoded frames.
Similarly, when using a memory type other than ``V4L2_MEMORY_MMAP``, the
client should make sure that each ``CAPTURE`` buffer is always queued with
the same backing memory for as long as the ``CAPTURE`` queue is streaming.
The reason for this is that V4L2 buffer indices can be used by drivers to
identify frames. Thus, if the backing memory of a reference frame is
submitted under a different buffer ID, the driver may misidentify it and
decode a new frame into it while it is still in use, resulting in corruption
of the following frames.
During the decoding, the decoder may initiate one of the special sequences, as
listed below. The sequences will result in the decoder returning all the
``CAPTURE`` buffers that originated from all the ``OUTPUT`` buffers processed
