Pixel format width is mistakenly aligned to surface align bytes and altering width to aligned value may force sensor mode change other than the requested one and also cause mismatch in width programmed between sensor and vi which can lead to capture errors. This patch removes width alignment and clamps width as per Tegra minimum and maximum limits. Signed-off-by:

This is only needed for drivers that do not use vb2_fop_release(). Note that vb2_queue_release() is *not* the counterpart of vb2_queue_init() as some drivers here seem to think. Also use vb2_video_unregister_device() to automatically stop streaming at unregister time for those drivers that set vdev->queue. Signed-off-by:

If a driver calls (_)vb2_fop_release(), then such a driver should also call vb2_video_unregister_device() instead of video_unregister_device(). This helper will call vb2_queue_release() if a filehandle is marked as owner of the queue. This ensures that at unregister time any streaming is cancelled and all buffers are returned to userspace. This is very useful for complex drivers since this stops all streaming in all subdevs in the pipeline controlled by this video device. Otherwise this would be delayed until the owner filehandle is closed, which can be quite some time later. Bonus points for ordering the includes :-) Signed-off-by:

vivid_meta_out_process() is setting `brightness`, `contrast`, `saturation` and `hue` using tpg_s_*(). This is wrong, since tpg_s_*() do not provide range checks. Using tpg_s_*() here also makes the control framework out-of-sync with the actual values. Use v4l2_ctrl_s_ctrl() instead.

The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice. Signed-off-by:

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced. For other error paths after this call, things are the same. Fix this by adding pm_runtime_put_noidle() after 'err_runtime_disable' label. But in this case, the error path after pm_runtime_put_sync() will decrease PM usage counter twice. Thus add an extra pm_runtime_get_noresume() in this path to balance PM counter. Signed-off-by:

Jacopo Mondi authored
When outputting SD-Core output through the TXA MIPI CSI-2 interface, the number of enabled data lanes should be reduced in order to guarantee that the two video formats produced by the SD-Core (480i and 576i) generate a MIPI CSI-2 link clock frequency compatible with the MIPI D-PHY specifications. Limit the number of enabled data lanes to 2, which is guaranteed to support 480i and 576i formats. Cache the number of enabled data lanes to be able to report it through the new get_mbus_config operation. Reviewed-by:

With the removal of the legacy g_mbus_config and s_mbus_config video operations, the sole users of V4L2_MBUS_* flags are now the newly introduced get_mbus_config and set_mbus_config pad operations. As the semantic of the new operations differs from the semantic of the legacy ones, add a usage note in the v4l2-mediabus.h header to specify how to use the flags. Also add a TODO note to record that we intend to replace the existing flags with fields, to prevent users from mixing conflicting values in a single operation call. Signed-off-by:

Move the PXA camera driver to use the new set_mbus_config pad operation. For this platform the change is not only cosmetic, as the pxa driver is currently the only driver in mainline to make use of the g_mbus_config and s_mbus_config video operations. The existing driver semantic is the following: - Collect all supported mbus config flags from the remote end - Match them with the supported PXA mbus configuration flags - If the remote subdevice allows multiple options for for VSYNC, HSYNC and PCLK polarity, use platform data requested settings The semantic of the new get_mbus_config and set_mbus_config differs from the corresponding video ops, particularly in the fact get_mbus_config reports the current mbus configuration and not the set of supported configuration options, with set_mbus_config always reporting the actual mbus configuration applied to the remote subdevice. Adapt the driver to perform the following - Set the remote subdevice mbus configuration according to the PXA platform data preferences. - If the applied configuration differs from the requested one (i.e. the remote subdevice does not allow changing one setting) make sure that - The remote end does not claim for DATA_ACTIVE_LOW, which seems not supported by the platform - The bus mastering roles match While at there remove a few checks performed on the media bus configuration at get_format() time as they do not belong there. Compile-tested only. Signed-off-by: -

Use the new get_mbus_config and set_mbus_config pad operations in place of the video operations currently in use. Compared to other drivers where the same conversion has been performed, ov6650 proved to be a bit more tricky, as the existing g_mbus_config implementation did not report the currently applied configuration but the set of all possible configuration options. Adapt the driver to support the semantic of the two newly introduced operations: - get_mbus_config reports the current media bus configuration - set_mbus_config applies only changes explicitly requested and updates the provided cfg parameter to report what has actually been applied to the hardware. Compile-tested only. Signed-off-by:

Move the existing users of the g_mbus_config video operation to use the newly introduced get_mbus_config pad operations. All the ported drivers report a static media bus configuration and do no support s_mbus_config so the operation implementation has not changed. Bridge drivers needs to call the new pad operation and will receive an -ENOICTLCMD when calling the old g_mbus_config video operation Signed-off-by:

General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented).
