media: core: export v4l2_translate_cmd

2025-07-11T17:27:28Z

video_translate_cmd() can be useful for drivers to convert between the VIDIOC_*32 and VIDIOC_ defines. Let's export it. Now that the function is exported, use this opportunity to rename the function with the v4l2_ prefix, that is less ambiguous than video_ The VIDIOC_*32 defines are not accessible by the drivers, they live in v4l2-compat-ioctl32.c.

media: v4l2-ctrls: Return the handler's error in v4l2_ctrl_handler_free()

2025-06-30T06:47:41Z

v4l2_ctrl_handler_free() used to return void but changing this to int, returning the handler's error code, enables the drivers to simply return the handler's error in this common error handling pattern: if (handler->error) return v4l2_ctrl_handler_free(handler); Suggested-by: Laurent Pinchart Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Reviewed-by: Hans Verkuil Signed-off-by: Hans Verkuil

media: vsp1: Add VSPX support

2025-06-18T07:20:47Z

Add support for VSPX, a specialized version of the VSP2 that transfers data to the ISP. The VSPX is composed of two RPF units to read data from external memory and an IIF instance that performs transfer towards the ISP. The VSPX is supported through a newly introduced vsp1_vspx.c file that exposes two interfaces: vsp1_vspx interface, declared in vsp1_vspx.h for the vsp1 core to initialize and cleanup the VSPX, and a vsp1_isp interface, declared in include/media/vsp1.h for the ISP driver to control the VSPX operations.

The functions: v4l2_jpeg_parse_huffman_tables() v4l2_jpeg_parse_quantization_tables() v4l2_jpeg_parse_scan_header() and v4l2_jpeg_parse_frame_header() were added in 2020 by commit 50733b5b9102 ("media: add v4l2 JPEG helpers") but have remained unused. Remove them. They're all just wrappers around an underlying set of helpers, which are all still called via v4l2_jpeg_parse_header(). Signed-off-by: Dr. David Alan Gilbert Signed-off-by: Hans Verkuil

media: common: Add v4l2_find_nearest_size_conditional()

2025-05-06T11:06:30Z

v4l2_find_nearest_size() returns a mode from sensor driver's mode list that is a best match width and height wise for the sensor. Some drivers have different set of available modes depending on the number of lanes. While this could be handled within a driver by providing different lists of modes, provide a helper v4l2_find_nearest_size_conditional() to ignore modes that aren't available. Also use size_t for the array index and remove extra commas while at it. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

Now that the VSP1 driver supports color spaces, expose them through the API used by the DU driver. This allows configuring the YCbCr encoding and quantization used by each plane, ensuring correct color rendering.
