- <para>For driver debugging purposes this ioctl allows test
-applications to query the driver about the chips present on the TV
-card. Regular applications must not use it. When you found a chip
-specific bug, please contact the linux-media mailing list (&v4l-ml;)
-so it can be fixed.</para>
-
- <para>To query the driver applications must initialize the
-<structfield>match.type</structfield> and
-<structfield>match.addr</structfield> or <structfield>match.name</structfield>
-fields of a &v4l2-dbg-chip-ident;
-and call <constant>VIDIOC_DBG_G_CHIP_IDENT</constant> with a pointer to
-this structure. On success the driver stores information about the
-selected chip in the <structfield>ident</structfield> and
-<structfield>revision</structfield> fields. On failure the structure
-remains unchanged.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_HOST</constant>,
-<structfield>match.addr</structfield> selects the nth non-&i2c; chip
-on the TV card. You can enumerate all chips by starting at zero and
-incrementing <structfield>match.addr</structfield> by one until
-<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.
-The number zero always selects the host chip, &eg; the chip connected
-to the PCI or USB bus.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_I2C_DRIVER</constant>,
-<structfield>match.name</structfield> contains the I2C driver name.
-For instance
-<constant>"saa7127"</constant> will match any chip
-supported by the saa7127 driver, regardless of its &i2c; bus address.
-When multiple chips supported by the same driver are present, the
-ioctl will return <constant>V4L2_IDENT_AMBIGUOUS</constant> in the
-<structfield>ident</structfield> field.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_I2C_ADDR</constant>,
-<structfield>match.addr</structfield> selects a chip by its 7 bit
-&i2c; bus address.</para>
-
- <para>When <structfield>match.type</structfield> is
-<constant>V4L2_CHIP_MATCH_AC97</constant>,
-<structfield>match.addr</structfield> selects the nth AC97 chip
-on the TV card. You can enumerate all chips by starting at zero and
-incrementing <structfield>match.addr</structfield> by one until
-<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.</para>
-
- <para>On success, the <structfield>ident</structfield> field will
-contain a chip ID from the Linux
-<filename>media/v4l2-chip-ident.h</filename> header file, and the
-<structfield>revision</structfield> field will contain a driver
-specific value, or zero if no particular revision is associated with
-this chip.</para>
-
- <para>When the driver could not identify the selected chip,
-<structfield>ident</structfield> will contain
-<constant>V4L2_IDENT_UNKNOWN</constant>. When no chip matched
-the ioctl will succeed but the
-<structfield>ident</structfield> field will contain
-<constant>V4L2_IDENT_NONE</constant>. If multiple chips matched,
-<structfield>ident</structfield> will contain
-<constant>V4L2_IDENT_AMBIGUOUS</constant>. In all these cases the
-<structfield>revision</structfield> field remains unchanged.</para>
-
- <para>This ioctl is optional, not all drivers may support it. It
-was introduced in Linux 2.6.21, but the API was changed to the
-one described here in 2.6.29.</para>
-
- <para>We recommended the <application>v4l2-dbg</application>
-utility over calling this ioctl directly. It is available from the
-LinuxTV v4l-dvb repository; see <ulink
-url="http://linuxtv.org/repo/">http://linuxtv.org/repo/</ulink> for
-access instructions.</para>

+There are currently two ways to register subdevices with the V4L2 core. The
+first (traditional) possibility is to have subdevices registered by bridge
+drivers. This can be done when the bridge driver has the complete information
+about subdevices connected to it and knows exactly when to register them. This
+is typically the case for internal subdevices, like video data processing units
+within SoCs or complex PCI(e) boards, camera sensors in USB cameras or connected
+to SoCs, which pass information about them to bridge drivers, usually in their
+platform data.
+
+There are however also situations where subdevices have to be registered
+asynchronously to bridge devices. An example of such a configuration is a Device
+Tree based system where information about subdevices is made available to the
+system independently from the bridge devices, e.g. when subdevices are defined
+in DT as I2C device nodes. The API used in this second case is described further
+below.
+
+Using one or the other registration method only affects the probing process, the
+run-time bridge-subdevice interaction is in both cases the same.

+In the asynchronous case subdevice probing can be invoked independently of the
+bridge driver availability. The subdevice driver then has to verify whether all
+the requirements for a successful probing are satisfied. This can include a
+check for a master clock availability. If any of the conditions aren't satisfied
+the driver might decide to return -EPROBE_DEFER to request further reprobing
+attempts. Once all conditions are met the subdevice shall be registered using
+the v4l2_async_register_subdev() function. Unregistration is performed using
+the v4l2_async_unregister_subdev() call. Subdevices registered this way are
+stored in a global list of subdevices, ready to be picked up by bridge drivers.
+
+Bridge drivers in turn have to register a notifier object with an array of
+subdevice descriptors that the bridge device needs for its operation. This is
+performed using the v4l2_async_notifier_register() call. To unregister the
+notifier the driver has to call v4l2_async_notifier_unregister(). The former of
+the two functions takes two arguments: a pointer to struct v4l2_device and a
+pointer to struct v4l2_async_notifier. The latter contains a pointer to an array
+of pointers to subdevice descriptors of type struct v4l2_async_subdev type. The
+V4L2 core will then use these descriptors to match asynchronously registered
+subdevices to them. If a match is detected the .bound() notifier callback is
+called. After all subdevices have been located the .complete() callback is
+called. When a subdevice is removed from the system the .unbind() method is

+V4L2 clocks
+-----------
+
+Many subdevices, like camera sensors, TV decoders and encoders, need a clock
+signal to be supplied by the system. Often this clock is supplied by the
+respective bridge device. The Linux kernel provides a Common Clock Framework for
+this purpose. However, it is not (yet) available on all architectures. Besides,
+the nature of the multi-functional (clock, data + synchronisation, I2C control)
+connection of subdevices to the system might impose special requirements on the
+clock API usage. E.g. V4L2 has to support clock provider driver unregistration
+while a subdevice driver is holding a reference to the clock. For these reasons
+a V4L2 clock helper API has been developed and is provided to bridge and
+subdevice drivers.
+
+The API consists of two parts: two functions to register and unregister a V4L2
+clock source: v4l2_clk_register() and v4l2_clk_unregister() and calls to control
+a clock object, similar to the respective generic clock API calls:
+v4l2_clk_get(), v4l2_clk_put(), v4l2_clk_enable(), v4l2_clk_disable(),
+v4l2_clk_get_rate(), and v4l2_clk_set_rate(). Clock suppliers have to provide
+clock operations that will be called when clock users invoke respective API
+methods.
+
+It is expected that once the CCF becomes available on all relevant
+architectures this API will be removed.
