Commit 1c1d86a1 ("[media] v4l2: always require v4l2_dev, rename parent to dev_parent") expects v4l2_dev to be always set. It converted most of the drivers using the parent field of video_device to v4l2_dev field. G2D driver did not set the parent field. Hence it got left out. Without this patch we get the following boot warning and G2D driver fails to register the video device.

The video encode/decode paths have duplicated logic between VIDIOC_TRY_FMT and VIDIOC_S_FMT that should be de-duped. Also, video decode reports V4L2_PIX_FMT_NV12MT_16X16 output format, regardless of what the actual output has been set at. Fix this. Signed-off-by:

FIMC-LITE subdevs have one sink pad and two source pads on which the image formats are always same. This patch implements missing format propagation from the sink pad to the source pads, to allow user space to negotiate TRY format on whole media pipeline involving FIMC-LITE.n subdevs. The subdev try_fmt helper is simplified.

Sylwester Nawrocki authored
This patch changes the firmware file names of the FIMC-IS subsystem. It is needed since there are different firmwares used across various SoC series, e.g. Exynos4 and Exynos5. Also the sensor specific "setfile" name is changed, to account for it depends on an image sensor and is also specific to the FIMC-IS and the SoC. This is a change for a driver merged in 3.10.

Add compatible property for the Exynos5250 and enable the frame start and frame end interrupts. These interrupts are needed for the Exynos5 FIMC-IS firmware. The driver enables those interrupt only where available, depending on the 'compatible' property. This can be optimized further, by exposing some API at the subdev driver, so the host driver can enable extra interrupts only for the image processing chains involving FIMC-IS. Signed-off-by:

This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE IP. A 'compatible' string is added for Exynos5250 compatible devices and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ register, masking output DMA buffer address slots. The frame interrupt is enabled so there are now 2 interrupts per frame. This likely can be optimized in future by using any status registers that allow to figure out what the last and the currently written frame buffer is. It would also be more reliable in cases where there are high interrupt service latencies. Signed-off-by:

The m2m-deinterlace, mem2mem_testdev and mx2_emmaprp drivers didn't set the v4l2_dev pointer in struct video_device, even though a v4l2_device was registered correctly. These days this v4l2_dev pointer must be set correctly, so this patch adds that for these three drivers. Signed-off-by:

Several functions in the sh_mobile_ceu_camera driver implement generic algorithms and can be re-used by other V4L2 camera host drivers too.

Add support for asynchronous subdevice probing, using the v4l2-async API. The legacy synchronous mode is still supported too, which allows to gradually update drivers and platforms. The selected approach adds a notifier for each struct soc_camera_device instance, i.e. for each video device node, even when there are multiple such instances registered with a single soc-camera host simultaneously.
