This function takes a pointer to an array of 'n' pin configuration entries, one for each pin being configured. This function could be called at times other than just subdevice initialization. ``init`` initialize the sensor registers to some sort of reasonable default values. Do not use for new drivers and should be removed in existing drivers. ``load_fw`` load firmware. ``reset`` generic reset command. The argument selects which subsystems to reset. Passing 0 will always reset the whole chip. Do not use for new drivers without discussing this first on the linux-media mailinglist. There should be no reason normally to reset a device. ``s_gpio`` set GPIO pins. Very simple right now, might need to be extended with a direction argument if needed. ``command`` called by in-kernel drivers in order to call functions internal to subdev drivers driver that have a separate callback. ``ioctl`` called at the end of ioctl() syscall handler at the V4L2 core. used to provide support for private ioctls used on the driver. ``compat_ioctl32`` called when a 32 bits application uses a 64 bits Kernel, in order to fix data passed from/to userspace. ``g_register`` callback for VIDIOC_DBG_G_REGISTER() ioctl handler code. ``s_register`` callback for VIDIOC_DBG_S_REGISTER() ioctl handler code. ``s_power`` puts subdevice in power saving mode (on == 0) or normal operation mode (on == 1). DEPRECATED. See Documentation/driver-api/media/camera-sensor.rst . pre_streamon and post_streamoff callbacks can be used for e.g. setting the bus to LP-11 mode before s_stream is called. ``interrupt_service_routine`` Called by the bridge chip's interrupt service handler, when an interrupt status has be raised due to this subdev, so that this subdev can handle the details. It may schedule work to be performed later. It must not sleep. **Called from an IRQ context**. ``subscribe_event`` used by the drivers to request the control framework that for it to be warned when the value of a control changes. ``unsubscribe_event`` remove event subscription from the control framework.h](j)}(hX**Definition**:: struct v4l2_subdev_core_ops { int (*log_status)(struct v4l2_subdev *sd);

to generate the clocks in Hz. An extra flags field allows device specific configuration regarding clock frequency dividers, etc. If not used, then set flags to 0. If the frequency is not supported, then -EINVAL is returned. ``g_std`` callback for VIDIOC_G_STD() ioctl handler code. ``s_std`` callback for VIDIOC_S_STD() ioctl handler code. ``s_std_output`` set v4l2_std_id for video OUTPUT devices. This is ignored by video input devices. ``g_std_output`` get current standard for video OUTPUT devices. This is ignored by video input devices. ``querystd`` callback for VIDIOC_QUERYSTD() ioctl handler code. ``g_tvnorms`` get :c:type:`v4l2_std_id` with all standards supported by the video CAPTURE device. This is ignored by video output devices. ``g_tvnorms_output`` get v4l2_std_id with all standards supported by the video OUTPUT device. This is ignored by video capture devices. ``g_input_status`` get input status. Same as the status field in the :c:type:`struct v4l2_input ` ``s_stream`` start (enabled == 1) or stop (enabled == 0) streaming on the sub-device. Failure on stop will remove any resources acquired in streaming start, while the error code is still returned by the driver. The caller shall track the subdev state, and shall not start or stop an already started or stopped subdev. Also see call_s_stream wrapper in v4l2-subdev.c. ``s_rx_buffer`` set a host allocated memory buffer for the subdev. The subdev can adjust **size** to a lower value and must not write more data to the buffer starting at **data** than the original value of **size**. ``pre_streamon`` May be called before streaming is actually started, to help initialising the bus. Current usage is to set a CSI-2 transmitter to LP-11 or LP-111 mode before streaming. See :c:type:`enum v4l2_subdev_pre_streamon_flags `. ``post_streamoff`` Called after streaming is stopped, but if and only if pre_streamon was called earlier. **Description** This callback is DEPRECATED. New drivers should instead implement :c:type:`v4l2_subdev_pad_ops.enable_streams ` and :c:type:`v4l2_subdev_pad_ops.disable_streams ` operations, and use v4l2_subdev_s_stream_helper for the :c:type:`v4l2_subdev_video_ops.s_stream ` operation to support legacy users. Drivers should also not call the .s_stream() subdev operation directly, but use the v4l2_subdev_enable_streams() and v4l2_subdev_disable_streams() helpers. pre_streamon shall return error if it cannot perform the operation as indicated by the flags argument. In particular, -EACCES indicates lack of support for the operation. The caller shall call post_streamoff for each successful call of pre_streamon.h](j)}(hX**Definition**:: struct v4l2_subdev_video_ops { int (*s_routing)(struct v4l2_subdev *sd, u32 input, u32 output, u32 config); int (*s_crystal_freq)(struct v4l2_subdev *sd, u32 freq, u32 flags); int (*g_std)(struct v4l2_subdev *sd, v4l2_std_id *norm); int (*s_std)(struct v4l2_subdev *sd, v4l2_std_id norm); int (*s_std_output)(struct v4l2_subdev *sd, v4l2_std_id std); int (*g_std_output)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*querystd)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_tvnorms)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_tvnorms_output)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_input_status)(struct v4l2_subdev *sd, u32 *status); int (*s_stream)(struct v4l2_subdev *sd, int enable); int (*s_rx_buffer)(struct v4l2_subdev *sd, void *buf, unsigned int *size); int (*pre_streamon)(struct v4l2_subdev *sd, u32 flags); int (*post_streamoff)(struct v4l2_subdev *sd); }; h](h)}(h**Definition**::h](j)}(h**Definition**h]h Definition}(hj3hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj3ubh:}(hj3hhhNhNubeh}(h]h ]h"]h$]h&]uh1hhi/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-subdev:644: ./include/media/v4l2-subdev.hhMhj3ubj>)}(hXstruct v4l2_subdev_video_ops { int (*s_routing)(struct v4l2_subdev *sd, u32 input, u32 output, u32 config); int (*s_crystal_freq)(struct v4l2_subdev *sd, u32 freq, u32 flags); int (*g_std)(struct v4l2_subdev *sd, v4l2_std_id *norm); int (*s_std)(struct v4l2_subdev *sd, v4l2_std_id norm); int (*s_std_output)(struct v4l2_subdev *sd, v4l2_std_id std); int (*g_std_output)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*querystd)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_tvnorms)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_tvnorms_output)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_input_status)(struct v4l2_subdev *sd, u32 *status); int (*s_stream)(struct v4l2_subdev *sd, int enable); int (*s_rx_buffer)(struct v4l2_subdev *sd, void *buf, unsigned int *size); int (*pre_streamon)(struct v4l2_subdev *sd, u32 flags); int (*post_streamoff)(struct v4l2_subdev *sd); };h]hXstruct v4l2_subdev_video_ops { int (*s_routing)(struct v4l2_subdev *sd, u32 input, u32 output, u32 config); int (*s_crystal_freq)(struct v4l2_subdev *sd, u32 freq, u32 flags); int (*g_std)(struct v4l2_subdev *sd, v4l2_std_id *norm); int (*s_std)(struct v4l2_subdev *sd, v4l2_std_id norm); int (*s_std_output)(struct v4l2_subdev *sd, v4l2_std_id std); int (*g_std_output)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*querystd)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_tvnorms)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_tvnorms_output)(struct v4l2_subdev *sd, v4l2_std_id *std); int (*g_input_status)(struct v4l2_subdev *sd, u32 *status); int (*s_stream)(struct v4l2_subdev *sd, int enable); int (*s_rx_buffer)(struct v4l2_subdev *sd, void *buf, unsigned int *size); int (*pre_streamon)(struct v4l2_subdev *sd, u32 flags); int (*post_streamoff)(struct v4l2_subdev *sd); };}hj3sbah}(h]h ]h"]h$]h&]hhuh1j=hi/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-subdev:644: ./include/media/v4l2-subdev.hhMhj3ubeh}(h]h ]h"]h$]h&]uh1jhj3hMhj3ubh)}(h **Members**h]j)}(hj3h]hMembers}(hj3hhhNhNubah}(h]h ]h"]h$]h&]uh1jhj3ubah}(h]h ]h"]h$]h&]uh1hhi/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-subdev:644: ./include/media/v4l2-subdev.hhMhj3ubjQ)}(hhh](jV)}(hT``s_routing`` see s_routing in audio_ops, except this version is for video devices. h](j\)}(h ``s_routing``h]h)}(hj4h]h s_routing}(hj 4hhhNhNubah}(h]h ]h"]h$]h&]uh1hhj4ubah}(h]h ]h"]h$]h&]uh1j[hi/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-subdev:644: ./include/media/v4l2-subdev.hhMhj4ubjv)}(hhh]h)}(hEsee s_routing in audio_ops, except this version is for video devices.h]hEsee s_routing in audio_ops, except this version is for video devices.}(hj!4hhhNhNubah}(h]h ]h"]h$]h&]uh1hhi/var/lib/git/docbuild/linux/Documentation/driver-api/media/v4l2-subdev:644: ./include/media/v4l2-subdev.hhMhj4ubah}(h]h ]h"]h$]h&]uh1juhj4ubeh}(h]h ]h"]h$]h&]uh1jUhj4hMhj3ubjV)}(hX``s_crystal_freq`` sets the frequency of the crystal used to generate the clocks in Hz.

The media bus configuration is usually retrieved from the firmware interface at sub-device probe time, immediately applied to the hardware and eventually adjusted by the driver. Remote sub-devices (usually video receivers) shall use this operation to query the transmitting end bus configuration in order to adjust their own one accordingly. Callers should make sure they get the most up-to-date as possible configuration from the remote end, likely calling this operation as close as possible to stream on time. The operation shall fail if the pad index it has been called on is not valid or in case of unrecoverable failures. The config argument has been memset to 0 just before calling the op. ``set_routing`` Enable or disable data connection routes described in the subdevice routing table. Subdevs that implement this operation must set the V4L2_SUBDEV_FL_STREAMS flag. ``enable_streams`` Enable the streams defined in streams_mask on the given source pad. Subdevs that implement this operation must use the active state management provided by the subdev core (enabled through a call to v4l2_subdev_init_finalize() at initialization time). Do not call directly, use v4l2_subdev_enable_streams() instead. ``disable_streams`` Disable the streams defined in streams_mask on the given source pad. Subdevs that implement this operation must use the active state management provided by the subdev core (enabled through a call to v4l2_subdev_init_finalize() at initialization time). Do not call directly, use v4l2_subdev_disable_streams() instead. **Description** Drivers that support only a single stream without setting the V4L2_SUBDEV_CAP_STREAMS sub-device capability flag can ignore the mask argument.

Never call these internal ops from within a driver! ``ctrl_handler`` The control handler of this subdev. May be NULL. ``name`` Name of the sub-device. Please notice that the name must be unique. ``grp_id`` can be used to group similar subdevs. Value is driver-specific ``dev_priv`` pointer to private data ``host_priv`` pointer to private data used by the device where the subdev is attached. ``devnode`` subdev device node ``dev`` pointer to the physical device, if any ``fwnode`` The fwnode_handle of the subdev, usually the same as either dev->of_node->fwnode or dev->fwnode (whichever is non-NULL). ``async_list`` Links this subdev to a global subdev_list or **notifier->done_list** list. ``async_subdev_endpoint_list`` List entry in async_subdev_endpoint_entry of :c:type:`struct v4l2_async_subdev_endpoint `. ``subdev_notifier`` A sub-device notifier implicitly registered for the sub- device using v4l2_async_register_subdev_sensor(). ``asc_list`` Async connection list, of :c:type:`struct v4l2_async_connection `.subdev_entry. ``pdata`` common part of subdevice platform data ``state_lock`` A pointer to a lock used for all the subdev's states, set by the driver. This is optional. If NULL, each state instance will get a lock of its own. ``privacy_led`` Optional pointer to a LED classdev for the privacy LED for sensors. ``active_state`` Active state for the subdev (NULL for subdevs tracking the state internally). Initialized by calling v4l2_subdev_init_finalize(). ``enabled_pads`` Bitmask of enabled pads used by v4l2_subdev_enable_streams() and v4l2_subdev_disable_streams() helper functions for fallback cases. ``s_stream_enabled`` Tracks whether streaming has been enabled with s_stream. This is only for call_s_stream() internal use. **Description** Each instance of a subdev driver should create this struct, either stand-alone or embedded in a larger struct. This structure should be initialized by v4l2_subdev_init() or one of its variants: v4l2_spi_subdev_init(), v4l2_i2c_subdev_init().h](j)}(hX **Definition**:: struct v4l2_subdev { #if defined(CONFIG_MEDIA_CONTROLLER);

The pad is identified by its index, while the streams are identified by the **streams_mask** bitmask. This allows enabling multiple streams on a pad at once. Enabling a stream that is already enabled isn't allowed. If **streams_mask** contains an already enabled stream, this function returns -EALREADY without performing any operation. Per-stream enable is only available for subdevs that implement the .enable_streams() and .disable_streams() operations. For other subdevs, this function implements a best-effort compatibility by calling the .s_stream() operation, limited to subdevs that have a single source pad.

modification. The helper iterates over the subdevice's sink pads, calls get_frame_desc on the remote subdevice connected to each sink pad, and collects the frame desc entries for streams that are routed to the given source pad according to the subdevice's routing table. Each entry is copied as-is from the upstream source, with the exception of the 'stream' field which is remapped to the source stream ID from the routing table. The frame desc type is taken from the first upstream source. If multiple sink pads are involved and the upstream sources report different frame desc types, -EPIPE is returned. The caller must hold the subdevice's active state lock. This variant is intended for drivers that need to perform additional work around the passthrough frame descriptor collection.
