A direct reference would be nice.

Is there a reason for having links from the CSI-2 receivers' source pads to
multiple video nodes? Isn't a single one enough?

Sorry, I forgot to reply before. Firmware sees each MIPI VC as a single
stream, for multiple VCs case, SW need create multiple firmware streams.

Yes, I understand that, but this does not explain why you have multiple
links between the source pads and video nodes. You can only capture one
stream at a time from a video node. The user needs to select the correct
video node related to a source pad, not to pick a random video node and
then figure out which link to enable.

The media graph does look impressive though. :-)

The user can select any of the video nodes to one source pad.
This figure shows that user have the capability to link any source pad
to any of the video node (in dotted line). In reality, only 1 link is
active (solid line).

Yes, that's how it's currently implemented but I don't think there's really
a reason to do that. Could you remove all but one link to each video node?

Ack. I generated this graph by media-ctl and dot automatically.
Let me try to draw a new one.

Thanks!

+
+Introduction
+============
+
+This file documents the Intel IPU6 (6th generation Image Processing Unit)
+Input System (MIPI CSI2 receiver) drivers located under
+drivers/media/pci/intel/ipu6.
+
+The Intel IPU6 can be found in certain Intel Chipsets but not in all SKUs:
+
+* TigerLake
+* JasperLake
+* AlderLake
+* RaptorLake
+* MeteorLake
+
+Intel IPU6 is made up of two components - Input System (ISYS) and Processing
+System (PSYS).
+
+The Input System mainly works as MIPI CSI2 receiver which receives and
+processes the imaging data from the sensors and outputs the frames to memory.
+
+There are 2 driver modules - intel_ipu6 and intel_ipu6_isys. intel_ipu6 is an
+IPU6 common driver which does PCI configuration, firmware loading and parsing,
+firmware authentication, DMA mapping and IPU-MMU (internal Memory mapping Unit)
+configuration. intel_ipu6_isys implements V4L2, Media Controller and V4L2
+sub-device interfaces. The IPU6 ISYS driver supports camera sensors connected
+to the IPU6 ISYS through V4L2 sub-device sensor drivers.
+
+.. Note:: See Documentation/driver-api/media/drivers/ipu6.rst for more
+	  information about the IPU6 hardware.
+
+
+Input system driver
+===================
+
+The input System driver mainly configures CSI2 DPHY, constructs the firmware
+stream configuration, sends commands to firmware, gets response from hardware
+and firmware and then returns buffers to user.
+The ISYS is represented as several V4L2 sub-devices - 'Intel IPU6 CSI2 $port',
+which provide V4L2 subdev interfaces to the user space, there are also several
+video nodes for each CSI-2 stream capture - 'Intel IPU6 ISYS capture $num' which
+provide interface to user to set formats, queue buffers and streaming.

+
+Capturing frames by IPU6 ISYS
+------------------------------------
+
+IPU6 ISYS is used to capture frames from the camera sensors connected to the
+CSI2 ports. The supported input formats of ISYS are listed in table below:
+
+.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
+
+.. flat-table::
+    :header-rows: 1
+
+    * - IPU6 ISYS supported input formats
+
+    * - RGB565, RGB888
+
+    * - UYVY8, YUYV8
+
+    * - RAW8, RAW10, RAW12
+
+Here is an example of IPU6 ISYS raw capture on Dell XPS 9315 laptop. On this
+machine, ov01a10 sensor is connected to IPU ISYS CSI2 port 2, which can
+generate images at sBGGR10 with resolution 1280x800.
+
+Using the media controller APIs, we can configure ov01a10 sensor by
+media-ctl [#f1]_ and yavta [#f2]_ to transmit frames to IPU6 ISYS.
+
+.. code-block:: none
+
+    # Example 1 capture frame from ov01a10 camera sensor
+    # This example assumes /dev/media0 as the IPU ISYS media device
+    export MDEV=/dev/media0
+
+    # Establish the link for the media devices using media-ctl
+    media-ctl -d $MDEV -l "\"ov01a10 3-0036\":0 -> \"Intel IPU6 CSI2 2\":0[1]"
+
+    # Set the format for the media devices
+    media-ctl -d $MDEV -V "ov01a10:0 [fmt:SBGGR10/1280x800]"
+    media-ctl -d $MDEV -V "Intel IPU6 CSI2 2:0 [fmt:SBGGR10/1280x800]"
+    media-ctl -d $MDEV -V "Intel IPU6 CSI2 2:1 [fmt:SBGGR10/1280x800]"
+
+Once the media pipeline is configured, desired sensor specific settings
+(such as exposure and gain settings) can be set, using the yavta tool.
+
+e.g
+
+.. code-block:: none
+
+    # and that ov01a10 sensor is connected to i2c bus 3 with address 0x36
+    export SDEV=$(media-ctl -d $MDEV -e "ov01a10 3-0036")
+
+    yavta -w 0x009e0903 400 $SDEV
+    yavta -w 0x009e0913 1000 $SDEV
+    yavta -w 0x009e0911 2000 $SDEV
+
+Once the desired sensor settings are set, frame captures can be done as below.
+
+e.g
+
+.. code-block:: none
+
+    yavta --data-prefix -u -c10 -n5 -I -s 1280x800 --file=/tmp/frame-#.bin \
+          -f SBGGR10 $(media-ctl -d $MDEV -e "Intel IPU6 ISYS Capture 0")
+
+With the above command, 10 frames are captured at 1280x800 resolution with
+sBGGR10 format. The captured frames are available as /tmp/frame-#.bin files.
+
+Here is another example of IPU6 ISYS RAW and metadata capture from camera
+sensor ov2740 on Lenovo X1 Yoga laptop.
+
+.. code-block:: none
+
+    media-ctl -l "\"ov2740 14-0036\":0 -> \"Intel IPU6 CSI2 1\":0[1]"
+    media-ctl -l "\"Intel IPU6 CSI2 1\":1 -> \"Intel IPU6 ISYS Capture 0\":0[5]"
+    media-ctl -l "\"Intel IPU6 CSI2 1\":2 -> \"Intel IPU6 ISYS Capture 1\":0[5]"
+
+    # set routing
+    media-ctl -v -R "\"Intel IPU6 CSI2 1\" [0/0->1/0[1],0/1->2/1[1]]"
+
+    media-ctl -v "\"Intel IPU6 CSI2 1\":0/0 [fmt:SGRBG10/1932x1092]"
+    media-ctl -v "\"Intel IPU6 CSI2 1\":0/1 [fmt:GENERIC_8/97x1]"
+    media-ctl -v "\"Intel IPU6 CSI2 1\":1/0 [fmt:SGRBG10/1932x1092]"
+    media-ctl -v "\"Intel IPU6 CSI2 1\":2/1 [fmt:GENERIC_8/97x1]"
+
+    CAPTURE_DEV=$(media-ctl -e "Intel IPU6 ISYS Capture 0")
+    ./yavta --data-prefix -c100 -n5 -I -s1932x1092 --file=/tmp/frame-#.bin \
+    -f SGRBG10 ${CAPTURE_DEV}
+
+    CAPTURE_META=$(media-ctl -e "Intel IPU6 ISYS Capture 1")
+    ./yavta --data-prefix -c100 -n5 -I -s97x1 -B meta-capture \
