Use the driver mutex to protect s_stream() operations. This will become more relevant once the sensor will support more formats and set_format() could be issue concurrently to s_stream(). Signed-off-by:

Implement the .enum_frame_size subdev pad operation. As the driver only supports one format and one resolution at the moment the implementation is trivial. Signed-off-by:

Rename __sensor_init() function to ov5647_set_mode() as the function is a regular one and the double underscores prefix shall be removed, and then move it to program the mode at s_stream(1) time, not at sensor power up. Break out from __sensor_init() the stream_off() operation call at sensor power up to coax the lanes in LP-11 state. Signed-off-by:

The ov5647_read()/ov5647_write() return in case of success the number of bytes read or written respectively. This requires callers to check if the return value is less than zero to detect an error. Unfortunately, in several places, callers directly return the result of a read/write call, causing issues when the returned valued is checked to be different from zero to detect an error. Fix this by returning zero if i2c_master_send() and i2c_master_read() return a positive value (the number of bytes written or read). Signed-off-by:

The driver has some obvious style issues which are worth fixing before expanding the driver capabilities. Fix: - Variable declaration order - Function parameters alignment - Multi-line comments and spurious line breaks - Use lowercase for hexadecimal values - > 80 cols lines Cosmetic change, no functional changes intended.

There's no way to query the subdevice for the supported resolutions. Add set_fmt and get_fmt implementations. Since there's only one format supported set_fmt does nothing and get returns single format. Signed-off-by:

The "channel" is added to the "dev->channels" but then if v4l2_m2m_ctx_init() fails then we free "channel" but it's still on the list so it could lead to a use after free.

If the CEC device was unregistered, then add EPOLLPRI to the poll() mask. Otherwise a select() that only waits for exceptions will not wake up. A select() that waits for read and/or write events *will* wake up on an EPOLLERR, but not (for some reason) if it just waits for exceptions. Strangly the epoll functionality will wakeup on EPOLLERR if you just wait for an exception, so in this respect select() and epoll differ. In the end it doesn't really matter, what matters is that polling file handles are woken up on device unregistration. Signed-off-by:

When unregistering a V4L2 device node, make sure any filehandles that are waiting for an event are woken up. Add v4l2_event_wake_all() to v4l2-event.c and call it from video_unregister_device(). Otherwise userspace might never know that a device node was removed. [hverkuil: checkpatch: replaced 'if (vdev == NULL)' by 'if (!vdev)'] Signed-off-by:

do_poll()/do_select() seem to set the _qproc member of poll_table to NULL the first time they are called on a given table, making subsequent calls of poll_wait() on that table no-ops. This is a problem for mem2mem which calls poll_wait() on the V4L2 queues' waitqueues only when a queue-related event is requested, which may not necessarily be the case during the first poll. For instance, a stateful decoder is typically only interested in EPOLLPRI events when it starts, and will switch to listening to both EPOLLPRI and EPOLLIN after receiving the initial resolution change event and configuring the CAPTURE queue. However by the time that switch happens and v4l2_m2m_poll_for_data() is called for the first time, poll_wait() has become a no-op and the V4L2 queues waitqueues thus cannot be registered. Fix this by moving the registration to v4l2_m2m_poll() and do it whether or not one of the queue-related events are requested. Signed-off-by:

This is a problem for vb2 which calls poll_wait() on the V4L2 queues' waitqueues only when a queue-related event is requested, which may not necessarily be the case during the first poll. Fix this by making the call to poll_wait() happen first thing and unconditionally in vb2_core_poll(). Signed-off-by:

Tegra VI/CSI hardware don't have native 8 lane capture support. Each CSI port has max 4 lanes only. So for x8 captures, consecutive ports are ganged up for left half and right half captures on to each x4 ports with buffer offsets based on source image split width to align side-by-side. All ports in gang are configured together during the corresponding video device node streaming for x8 captures. x8 capture with gang ports are supported with HDMI-to-CSI bridges where they split 4K image into left half onto one x4 port and right half onto second x4 port.

Implement V4L2 device notify callback to handle V4L2_EVENT_SOURCE_CHANGE event from subdevices. HDMI-to-CSI bridge drivers trigger V4L2_EVENT_SOURCE_CHANGE when source DV timing changes are detected or when HDMI hotplug happens. Runtime source parameter changes during active streaming is not allowed and Tegra video driver calls vb2_queue_error to signal a fatal error if a notification of this event happens during an active streaming.

Sowjanya Komatineni authored
VI Pixel transforms converts source pixel data to selected destination pixel formats in memory and aligns properly. YUV and RGB formats need this pixel transform to be enabled. RAW formats use T_R16_I destination pixel format in memory and does not need pixel transform as they support direct write to memory. So, this patch enables pixel transform for YUV and RGB and keeps it bypass for RAW formats. Signed-off-by:

Currently try format implementation doesn't check if subdevice has get_selection ops implemented and returns -EINVAL on error from direct v4l2_subdev_call of get_selection. Selection API's are not mandatory for all V4L2 subdevices. This patch fixes it by adding v4l2_subdev_has_ops check prior to calling get_selection ops and continues with try or set format with zero crop settings for subdevices that don't have get_selection and returns -EINVAL only for subdevices that has get_selection ops.
