Too many '='s.

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?

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. :-)

+
+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]"
