media: v4l: vsp1: Use SPDX license headers Adopt the SPDX license identifier headers to ease license compliance management. All files in the driver are licensed under the GPLv2+ except for the vsp1_regs.h file which is licensed under the GPLv2. This is likely an oversight, but fixing this requires contacting the copyright owners and is out of scope for this patch. While at it fix the file descriptions to match file names where copy and paste error occurred.

[media] v4l: Renesas R-Car VSP1 driver The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage.

[media] v4l: vsp1: uds: Fix scaling of alpha layer Pixel color components can be scaled using either bilinear interpolation or a multitap filter. The multitap filter provides better results, but can't be selected when the alpha layer need to be scaled down by more than 1/2. Disable alpha scaling when the input has a fixed alpha value, and program the UDS to output a fixed alpha value in that case. This ensures the multitap filter will be used whenever possible.

media: vsp1: Adapt entities to configure into a body Currently the entities store their configurations into a display list. Adapt this such that the code can be configured into a body directly, allowing greater flexibility and control of the content. All users of vsp1_dl_list_write() are removed in this process, thus it too is removed. A helper, vsp1_dl_list_get_body0() is provided to access the internal body0 from the display list.
