[media] media: ti-vpe: Add CAL v4l2 camera capture driver

The Camera Adaptation Layer (CAL) is a block which consists of a dual port CSI2/MIPI camera capture engine. Port #0 can handle CSI2 camera connected to up to 4 data lanes. Port #1 can handle CSI2 camera connected to up to 2 data lanes. The driver implements the required API/ioctls to be V4L2 compliant. Driver supports the following: - V4L2 API using DMABUF/MMAP buffer access based on videobuf2 api - Asynchronous sensor sub device registration - DT support Signed-off-by: Benoit Parrot <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
