Deprecate the cpia2 driver. This driver does not use the vb2 framework for video streaming, instead it implements its own version. We want to get rid of these old drivers, so deprecated it for future removal. Signed-off-by:

Rename 'videobuf' to 'vb2' in the comment. This avoids confusing terminology since 'videobuf' typically refers to the old vb1 framework. Signed-off-by:

These terms typically refer to the old version 1 videobuf framework. It is confusing to use them for the vb2 framework, so reword these comments. Signed-off-by:

Remove the dead code under NGENE_V4L. Among others, this removes references to the old videobuf framework that isn't actually used by this driver. Signed-off-by:

Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP core found on i.MX8MP SoC. The processor core applies a programmable geometrical transformation on input images to correct distorsion introduced by lenses. The transformation function is exposed as a grid map with 16x16 pixel macroblocks indexed using X, Y vertex coordinates. The dewarping map can be set from application through a dedicated v4l2 control. If not set or invalid, the driver computes an identity map prior to starting the processing engine. The driver supports scaling, cropping and pixel format conversion. Signed-off-by:
