-
- <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, ⪚ 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>

...
sink of the link. Subdev drivers are also free to use this function to
perform the checks mentioned above in addition to their own checks.
-A device (bridge) driver needs to register the v4l2_subdev with the
-v4l2_device:
+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 synchronous case a device (bridge) driver needs to register the
+v4l2_subdev with the v4l2_device:
int err = v4l2_device_register_subdev(v4l2_dev, sd);
You can call an ops function either directly:
- err = sd->ops->core->g_chip_ident(sd, &chip);
+ err = sd->ops->core->g_std(sd, &norm);
but it is better and easier to use this macro:
- err = v4l2_subdev_call(sd, core, g_chip_ident, &chip);
+ err = v4l2_subdev_call(sd, core, g_std, &norm);
The macro will to the right NULL pointer checks and returns -ENODEV if subdev
-is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_chip_ident is
-NULL, or the actual result of the subdev->ops->core->g_chip_ident ops.
+is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_std is
+NULL, or the actual result of the subdev->ops->core->g_std ops.
It is also possible to call all or a subset of the sub-devices:
- v4l2_device_call_all(v4l2_dev, 0, core, g_chip_ident, &chip);
+ v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm);
Any subdev that does not support this ops is skipped and error results are
ignored. If you want to check for errors use this:
- err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_chip_ident, &chip);
+ err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
Any error except -ENOIOCTLCMD will exit the loop with that error. If no
errors (except -ENOIOCTLCMD) occurred, then 0 is returned.
up the device, but once the subdev is registered it is completely transparent.
+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
+called. All three callbacks are optional.
+
+
V4L2 sub-device userspace API
-----------------------------
The default video_device_release() callback just calls kfree to free the
allocated memory.
+There is also a video_device_release_empty() function that does nothing
+(is empty) and can be used if the struct is embedded and there is nothing
+to do when it is released.
+
You should also set these fields:
-- v4l2_dev: set to the v4l2_device parent device.
+- v4l2_dev: must be set to the v4l2_device parent device.
- name: set to something descriptive and unique.
If you want to have a separate priority state per (group of) device node(s),
then you can point it to your own struct v4l2_prio_state.
-- parent: you only set this if v4l2_device was registered with NULL as
+- dev_parent: you only set this if v4l2_device was registered with NULL as
the parent device struct. This only happens in cases where one hardware
device has multiple PCI devices that all share the same v4l2_device core.
The cx88 driver is an example of this: one core v4l2_device struct, but
- it is used by both an raw video PCI device (cx8800) and a MPEG PCI device
- (cx8802). Since the v4l2_device cannot be associated with a particular
- PCI device it is setup without a parent device. But when the struct
- video_device is setup you do know which parent PCI device to use.
+ it is used by both a raw video PCI device (cx8800) and a MPEG PCI device

+ at the same time it is setup without a parent device. But when the struct
+ video_device is initialized you *do* know which parent PCI device to use and
+ so you set dev_device to the correct PCI device.
- flags: optional. Set to V4L2_FL_USE_FH_PRIO if you want to let the framework
handle the VIDIOC_G/S_PRIORITY ioctls. This requires that you use struct
An example on how the V4L2 events may be used can be found in the OMAP
3 ISP driver (drivers/media/platform/omap3isp).

+
+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.
这些结构体定义如下：
struct v4l2_subdev_core_ops {
- int (*g_chip_ident)(struct v4l2_subdev *sd, struct v4l2_dbg_chip_ident *chip);
int (*log_status)(struct v4l2_subdev *sd);
int (*init)(struct v4l2_subdev *sd, u32 val);
...
注册之设备后，可通过以下方式直接调用其操作函数：
- err = sd->ops->core->g_chip_ident(sd, &chip);
+ err = sd->ops->core->g_std(sd, &norm);
但使用如下宏会比较容易且合适：
- err = v4l2_subdev_call(sd, core, g_chip_ident, &chip);
+ err = v4l2_subdev_call(sd, core, g_std, &norm);
这个宏将会做 NULL 指针检查，如果 subdev 为 NULL，则返回-ENODEV；如果
-subdev->core 或 subdev->core->g_chip_ident 为 NULL，则返回 -ENOIOCTLCMD；
-否则将返回 subdev->ops->core->g_chip_ident ops 调用的实际结果。
+subdev->core 或 subdev->core->g_std 为 NULL，则返回 -ENOIOCTLCMD；
+否则将返回 subdev->ops->core->g_std ops 调用的实际结果。
有时也可能同时调用所有或一系列子设备的某个操作函数：
- v4l2_device_call_all(v4l2_dev, 0, core, g_chip_ident, &chip);
+ v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm);
任何不支持此操作的子设备都会被跳过，并忽略错误返回值。但如果你需要
检查出错码，则可使用如下函数：
- err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_chip_ident, &chip);
+ err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
除 -ENOIOCTLCMD 外的任何错误都会跳出循环并返回错误值。如果（除 -ENOIOCTLCMD
外）没有错误发生，则返回 0。
