Destructive overlay support (i.e. where the video frame is DMA-ed straight into a framebuffer) is effectively dead. It was a necessary evil in the early days when computers were not fast enough to copy SDTV video frames around, but today that's no longer a problem. It requires access to the framebuffer memory, which is a bad idea and very hard to do safely. In addition, in drm it is today almost impossible to get hold of the framebuffer address. So drop support for this. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
