The imx_media_video_dev structure stores the active format on the video node in an instance of v4l2_format. This wastes memory when all we need is the information contained in the smaller v4l2_pix_format sub-structure. Replace v4l2_format by v4l2_pix_format to save memory. Signed-off-by:

When the video device is registered, it can get used by userspace immediately. Its initialization must thus be fully complete. Ensure this by registering the video device after all initialization steps. Signed-off-by:

Overwriting the whole video_device isn't future-proof as it would overwrite any field initialized by video_device_alloc(). Furthermore, the current implementation modifies the global template video_device as if it were a per-instance structure, which is bad practice. To fix all this, initialize the video device programmatically in imx_media_capture_device_init(). Signed-off-by:

Move the initialization of the vb2 queue and the control handler to the imx_media_capture_device_init() function. There's no need to delay them until the registration time. Signed-off-by:

The v4l2_capability bus_info field is meant to locate the device in the system. Using a subdev name isn't a good fit, the device name is a much better option. Use it. Signed-off-by:

Laurent Pinchart authored
The imx-media-capture helpers operate a video device node, but abuse the v4l2_* subdev print functions to log messages. We have a struct device pointer available, use it instead with the dev_* functions. This reduces dependencies from imx-media-capture to the connected subdev. Signed-off-by:

All drivers use 640x480 as the default size, but they all hardcode those values. Create two global macros named IMX_MEDIA_DEF_PIX_WIDTH and IMX_MEDIA_DEF_PIX_HEIGHT to store the default size, and use them through the code. Signed-off-by:

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag.

Video engine uses eclk and vclk for its clock sources and its reset control is coupled with eclk so the current clock enabling sequence works like below. Enable eclk De-assert Video Engine reset 10ms delay Enable vclk It introduces improper reset on the Video Engine hardware and eventually the hardware generates unexpected DMA memory transfers that can corrupt memory region in random and sporadic patterns. This issue is observed very rarely on some specific AST2500 SoCs but it causes a critical kernel panic with making a various shape of signature so it's extremely hard to debug. Moreover, the issue is observed even when the video engine is not actively used because udevd turns on the video engine hardware for a short time to make a query in every boot. To fix this issue, this commit changes the clock handling logic to make the reset de-assertion triggered after enabling both eclk and vclk. Also, it adds clk_unprepare call for a case when probe fails. clk: ast2600: fix reset settings for eclk and vclk Video engine reset setting should be coupled with eclk to match it with the setting for previous Aspeed SoCs which is defined in clk-aspeed.c since all Aspeed SoCs are sharing a single video engine driver. Also, reset bit 6 is defined as 'Video Engine' reset in datasheet so it should be de-asserted when eclk is enabled. This commit fixes the setting.

When setting the source media bus code in the resizer, we first check that the current media bus code in the source is yuv encoded format. This is done by retrieving the data from the formats list of the isp entity. This cause a crash when the media bus code on the source is YUYV8_1_5X8 which is not supported by the isp entity. Instead we should test the sink format of the resizer which is guaranteed to be supported by the isp entity.
