 Once the media pipeline is configured, desired sensor specific settings
 (such as exposure and gain settings) can be set, using the yavta tool.

+    yavta -w 0x009e0911 2046 $SDEV
 
 Once the desired sensor settings are set, frame captures can be done as below.
 
 e.g
 
-yavta --data-prefix -u -c10 -n5 -I -s2592x1944 --file=/tmp/frame-#.bin \
-      -f IPU3_SGRBG10 $(media-ctl -d $MDEV -e "ipu3-cio2 0")

 With the above command, 10 frames are captured at 2592x1944 resolution, with
 sGRBG10 format and output as IPU3_SGRBG10 format.

+Writing camera sensor drivers
+=============================
+
+CSI-2
+-----
+
+Please see what is written on :ref:`MIPI_CSI_2`.
+
+Handling clocks
+---------------
+
+Camera sensors have an internal clock tree including a PLL and a number of
+divisors. The clock tree is generally configured by the driver based on a few
+input parameters that are specific to the hardware:: the external clock frequency
+and the link frequency. The two parameters generally are obtained from system
+firmware. No other frequencies should be used in any circumstances.
+
+The reason why the clock frequencies are so important is that the clock signals
+come out of the SoC, and in many cases a specific frequency is designed to be
+used in the system. Using another frequency may cause harmful effects
+elsewhere. Therefore only the pre-determined frequencies are configurable by the
+user.
+
+Frame size
+----------
+
+There are two distinct ways to configure the frame size produced by camera
+sensors.
+
+Freely configurable camera sensor drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Freely configurable camera sensor drivers expose the device's internal
+processing pipeline as one or more sub-devices with different cropping and
+scaling configurations. The output size of the device is the result of a series
+of cropping and scaling operations from the device's pixel array's size.
+
+An example of such a driver is the smiapp driver (see drivers/media/i2c/smiapp).
+
+Register list based drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Register list based drivers generally, instead of able to configure the device
+they control based on user requests, are limited to a number of preset
+configurations that combine a number of different parameters that on hardware
+level are independent. How a driver picks such configuration is based on the
+format set on a source pad at the end of the device's internal pipeline.
+
+Most sensor drivers are implemented this way, see e.g.
+drivers/media/i2c/imx319.c for an example.
+
+Frame interval configuration
+----------------------------
+
+There are two different methods for obtaining possibilities for different frame
+intervals as well as configuring the frame interval. Which one to implement
+depends on the type of the device.
+
+Raw camera sensors
+~~~~~~~~~~~~~~~~~~
+
+Instead of a high level parameter such as frame interval, the frame interval is
+a result of the configuration of a number of camera sensor implementation
+specific parameters. Luckily, these parameters tend to be the same for more or
+less all modern raw camera sensors.
+
+The frame interval is calculated using the following equation::
+
+	frame interval = (analogue crop width + horizontal blanking) *
+			 (analogue crop height + vertical blanking) / pixel rate
+
+The formula is bus independent and is applicable for raw timing parameters on
+large variety of devices beyond camera sensors. Devices that have no analogue
+crop, use the full source image size, i.e. pixel array size.
+
+Horizontal and vertical blanking are specified by ``V4L2_CID_HBLANK`` and
+``V4L2_CID_VBLANK``, respectively. The unit of these controls are lines. The
+pixel rate is specified by ``V4L2_CID_PIXEL_RATE`` in the same sub-device. The
+unit of that control is Hz.
+
+Register list based drivers need to implement read-only sub-device nodes for the
+purpose. Devices that are not register list based need these to configure the
+device's internal processing pipeline.
+
+The first entity in the linear pipeline is the pixel array. The pixel array may
+be followed by other entities that are there to allow configuring binning,
+skipping, scaling or digital crop :ref:`v4l2-subdev-selections`.
+
+USB cameras etc. devices
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+USB video class hardware, as well as many cameras offering a similar higher
+level interface natively, generally use the concept of frame interval (or frame
+rate) on device level in firmware or hardware. This means lower level controls
+implemented by raw cameras may not be used on uAPI (or even kAPI) to control the
+frame interval on these devices.
+
+Power management
+----------------
+
+Always use runtime PM to manage the power states of your device. Camera sensor
+drivers are in no way special in this respect: they are responsible for
+controlling the power state of the device they otherwise control as well. In
+general, the device must be powered on at least when its registers are being
+accessed and when it is streaming.
+
+Existing camera sensor drivers may rely on the old
+:c:type:`v4l2_subdev_core_ops`->s_power() callback for bridge or ISP drivers to
+manage their power state. This is however **deprecated**. If you feel you need
+to begin calling an s_power from an ISP or a bridge driver, instead please add
+runtime PM support to the sensor driver you are using. Likewise, new drivers
+should not use s_power.
+
+Please see examples in e.g. ``drivers/media/i2c/ov8856.c`` and
+``drivers/media/i2c/smiapp/smiapp-core.c``. The two drivers work in both ACPI
+and DT based systems.
+
+Control framework
+~~~~~~~~~~~~~~~~~
+
+``v4l2_ctrl_handler_setup()`` function may not be used in the device's runtime
+PM ``runtime_resume`` callback, as it has no way to figure out the power state
+of the device. This is because the power state of the device is only changed
+after the power state transition has taken place. The ``s_ctrl``callback can be
+used to obtain device's power state after the power state transition:
+
+.. c:function::
+	int pm_runtime_get_if_in_use(struct device *dev);
+
+The function returns a non-zero value if it succeeded getting the power count or
+runtime PM was disabled, in either of which cases the driver may proceed to
+access the device.

-Device Naming
-=============
+Controlling a hardware peripheral via V4L2
+==========================================
+
+Hardware that is supported using the V4L2 uAPI often consists of multiple
+devices or peripherals, each of which have their own driver.
+
+The bridge driver exposes one or more V4L2 device nodes
+(see :ref:`v4l2_device_naming`).
+
+There are other drivers providing support for other components of
+the hardware, which may also expose device nodes, called V4L2 sub-devices.
+
+When such V4L2 sub-devices are exposed, they allow controlling those
+other hardware components - usually connected via a serial bus (like
+I²C, SMBus or SPI). Depending on the bridge driver, those sub-devices
+can be controlled indirectly via the bridge driver or explicitly via
+the :ref:`Media Controller <media_controller>` and via the
+:ref:`V4L2 sub-devices <subdev>`.
+
+The devices that require the use of the
+:ref:`Media Controller <media_controller>` are called **MC-centric**
+devices. The devices that are fully controlled via V4L2 device nodes
+are called **video-node-centric**.
+
+Userspace can check if a V4L2 hardware peripheral is MC-centric by
+calling :ref:`VIDIOC_QUERYCAP` and checking the
+:ref:`device_caps field <device-capabilities>`.
+
+If the device returns ``V4L2_CAP_IO_MC`` flag at ``device_caps``,
+then it is MC-centric, otherwise, it is video-node-centric.
+
+It is required for MC-centric drivers to identify the V4L2
+sub-devices and to configure the pipelines via the
+:ref:`media controller API <media_controller>` before using the peripheral.
+Also, the sub-devices' configuration shall be controlled via the
+:ref:`sub-device API <subdev>`.
+
+.. note::
+
+   A video-node-centric may still provide media-controller and
+   sub-device interfaces as well.
+
+  However, in that case the media-controller and the sub-device
+  interfaces are read-only and just provide information about the
+  device. The actual configuration is done via the video nodes.
+
+.. _v4l2_device_naming:
+
+V4L2 Device Node Naming

 V4L2 drivers are implemented as kernel modules, loaded manually by the
 system administrator or automatically when a device is first discovered.

+is compiled with the kernel option CONFIG_VIDEO_FIXED_MINOR_RANGES.
+In that case minor numbers are allocated in ranges depending on the

+======================== ====================================================
+Default device node name Usage
+======================== ====================================================
+``/dev/videoX``		 Video and metadata for capture/output devices
+``/dev/vbiX``		 Vertical blank data (i.e. closed captions, teletext)
+``/dev/radioX``		 Radio tuners and modulators
+``/dev/swradioX``	 Software Defined Radio tuners and modulators
+``/dev/v4l-touchX``	 Touch sensors
+``/dev/v4l-subdevX``	 Video sub-devices (used by sensors and other
+			 components of the hardware peripheral)\ [#]_
+======================== ====================================================
+
+Where ``X`` is a non-negative integer.
+
+.. note::
+
+   1. The actual device node name is system-dependent, as udev rules may apply.
+   2. There is no guarantee that ``X`` will remain the same for the same
+      device, as the number depends on the device driver's probe order.
+      If you need an unique name, udev default rules produce
+      ``/dev/v4l/by-id/`` and ``/dev/v4l/by-path/`` directories containing
+      links that can be used uniquely to identify a V4L2 device node::
