Move __fimc_videoc_querycap() function to the common exynos4-is-common.ko module so it don't need to be reimplemented in multiple video node drivers of the exynos4-is. Signed-off-by:

Remove duplicated code in the vidioc_try_fmt and vidioc_s_fmt handlers. This is a pre-requsite to allow successful fimc.capture video open even if its corresponding media entities are not linked into a complete pipeline. Signed-off-by:

FIMC-LITE devices are never looked up by iterating over all platform devices with bus_for_each_device() as these IP blocks are available only on dt-only Exynos SoC platforms. Signed-off-by:

Protect the fimc/fimc-lite video nodes unregistration with their video lock. This prevents a kernel crash when e.g. udev opens a video node right after the driver registers it and then the driver tries to unregister it and defers its probing. Using video_is_unregistered() together with the video mutex allows safe unregistration of the video nodes at any time. Signed-off-by:

It's not a critical error to call __fimc_pipeline_close() with missing sensor subdev entity. Replace WARN_ON() with pr_warn() and return 0 instead of -EINVAL to fix control flow in some conditions. Signed-off-by:

This enumeration is now private to exynos4-is and the exynos5 camera subsystem driver may have the subdevs handling designed differently. Signed-off-by:

Sylwester Nawrocki authored
Use pm_runtime_put_sync() instead of pm_runtime_put() to avoid races in handling the 'state' bit flags when the fimc-capture drivers' runtime_resume callback is called from the PM workqueue. Signed-off-by:

Sylwester Nawrocki authored
Remove driver private video node reference counters and use entity->use_count instead. This makes the video pipelines power handling more similar to the method used in omap3isp driver. Now the graph mutex is taken always after the video mutex, as it is not possible to ensure apposite order at the all modules. Signed-off-by:

This patch moves the code for inheriting subdev v4l2 controls on the FIMC video capture nodes from open()/close() fops to the link setup notification callback. This allows for the state of the FIMC controls to be always kept, in opposite to the current situation when it is lost when last process closes video device. There is no visible change for the original V4L2 compliant interface. For the MC aware applications (user_subdev_api == true) inheriting of the controls is dropped, since there can be same controls on the subdevs withing single pipeline, now when the ISP (FIMC-IS) is also used. This patch is a prerequisite to allow /dev/video device to be opened without errors even if there is no media links connecting it to an image source (sensor) subdev. This is required for a libv4l2 plugin to be initialized while a video node is opened and it also should be possible to always open the device to query the capabilities. Signed-off-by:

Fix to return a negative error code in the vb2_dma_contig_init_ctx() error handling case instead of 0, as done elsewhere in this function. Also vb2_dma_contig_init_ctx() return ERR_PTR() in case of error and never return NULL, so use IS_ERR() replace IS_ERR_OR_NULL(). Signed-off-by:

X-Patchwork-Delegate: mchehab@redhat.com There are a few cases where breaking the code into separate lines make it worse to read. However, on several places, breaking it to make checkpatch.pl happier is OK and improves code readability. So, break longer lines where that won't cause harm. Signed-off-by: -
