Clock control indirectly requires access to MFC device, so call it only if we are sure that the device exists in s5p_mfc_release function. s5p_mfc_remove() calls s5p_mfc_final_pm(), which releases all PM related resources, including clocks, so any call to clocks related functions is not valid after s5p_mfc_final_pm(). Fixes: d695c12c ("[media] media: s5p-mfc fix invalid memory access from s5p_mfc_release()") Signed-off-by:

Newer MFC hardware have internal clock gating feature, so additional software-triggered clock gating sometimes causes misbehavior of the MFC firmware and results in freeze or crash. This patch changes the driver to use software-triggered clock gating only when working with v5 MFC hardware, where it has been proven to work properly. Signed-off-by:

Currently, when incomplete frame is received in the middle of decoding, driver treats it as an error, so src/dst queue and clock are cleaned. Although it is obviously error case, it is needed to maintain video decoding in case of necessity. This patch supports skip incomplete frame to next. Signed-off-by:

When video file was decoded by H/W MFCv8. It occurred IOMMU page fault because of accessing abnormal memory of mfc ctx buf. So this patch supports buffer size of mfc context more.

The struct v4l2_device instance for the G-Scaler is not dyanmically allocated but a member of the struct gsc_dev. In fact, the assigned .release callback is video_device_release_empty(). But gsc_register_m2m_device() attempts to release the v4l2_device by calling video_device_release() in its error path. This is wrong since the v4l2_device wasn't allocated directly and will be freed once its parent struct gsc_dev is freed. While being there, rename the remaining goto label in the error path to something that better explains the error path cleanup. Signed-off-by:

The driver don't take into account the differences between packed, semi planar and multi planar formats when calculating the pixel format bytes per lines and image size values. This makes GStreamer to fail when the following formats are used NV12, NV21, NV16, NV61, YV12, I420 and Y42B: "gst_video_frame_map_id: failed to map video frame plane 1" Nicolas suggested to use the logic found in the Exynos FIMC v4l2 driver since does this correctly. So this patch changes the bytes per line and image size calculation according to what's done in this media driver. After this patch most supported formats work correctly. There are still issues with the NV21 and NV61 formats, but that seems to be a separate problem since NV12 and NV16 work and these formats use the same values. So this can be fixed as a follow-up and shouldn't be a blocker for this change that improves the driver's support. Suggested-by:

The driver exposes 32-bit A/XRGB 8-8-8-8 as supported format but testing shows that using this format produces frames with wrong colors. The test was done with the following GStreamer pipeline: $ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \ ! v4l2video3convert ! video/x-raw,format=xRGB ! videoconvert ! kmssink The manual seems to state that the Pixel Format are in Little Endianness so instead use the 32-bit BGRA/X 8-8-8-8 pixel format. This format works correctly when using the following pipeline: $ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \ ! v4l2video3convert ! video/x-raw,format=BGRx ! kmssink This change is similar to commit 7f2816e5 ("[media] s5p-fimc: Changed RGB32 to BGR32") that fixed the same issue on a different Samsung driver.

User-space applications can use the VIDIOC_REQBUFS ioctl to determine if a memory mapped, user pointer or DMABUF based I/O is supported by a driver. For example, GStreamer attempts to determine the I/O methods supported by the driver by doing many VIDIOC_REQBUFS ioctl calls with different memory types and count 0. And then the real VIDIOC_REQBUFS call with count == n is be made to allocate the buffers. But for count 0, the driver not only frees the buffers but also clears the format set before with VIDIOC_S_FMT. This is a problem since STREAMON fails if a format isn't set but GStreamer first sets a format and then tries to determine the supported I/O methods, so the format will be cleared on REQBUFS(0), before the call to STREAMON. To avoid this issue, only free the buffers on VIDIOC_REQBUFS(0) but don't clear the format. Since is completely valid to set the format and then do different calls to REQBUFS before a call to STREAMON. Signed-off-by:

The driver try_fmt handler prints a message each time that the image size has been changed due the maximum and minimum width and height. Since user-space can try different format and sizes, this logs a lot of unnecessary messages. Change the message log level to debug and while being there, also add a new line to the message.

For tiled format, we need to allocated a multiple of the row size. A good example is for 1280x720, wich get adjusted to 1280x736. In tiles, this mean Y plane is 20x23 and UV plane 20x12. Because of the rounding, the previous code would only have enough space to fit half of the last row. [mchehab@s-opensource.com: fix coding style] Signed-off-by:

When requesting the DMA channel it was mandatory that we do not have DMA resource nor valid DMA channel via DT. In this case the dma_request_slave_channel_compat() would fall back and request any channel with SW trigger. The same can be achieved with the dma_request_chan_by_mask() without the misleading use of the DMAengine API - implying that the omap3isp does need to have DMA resource or valid dma binding in DT.

When parsing the graph the driver loops over all endpoints using of_graph_get_next_endpoint(). The function handles reference counting of the passed and returned nodes, so the returned node's reference count must not be decreased manually in the normal path. Move the offending of_node_put() call to the error path that requires manual reference count handling. Reported-by:

The Rift CV1 Sensor has bInterfaceClass set to vendor specific, so we need an entry in uvc_ids to probe it. Just as the Rift DK2 IR tracker, it misreports the pixel format as YUYV instead of Y8. The sensor is configured with a low exposure time and high black level by default, so that only bright IR sources can be seen. Signed-off-by:

Update the TODOs explaining why these two drivers remain in staging. The reason is that these drivers rely on userspace to set the physical address, but that should come from the HDMI output driver. This in turn needs the upcoming HDMI notifier framework. Signed-off-by:
