The Camera Adaptation Layer (CAL) is a block which consists of a dual port CSI2/MIPI camera capture engine. This camera engine is currently found on DRA72xx family of devices. 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 Currently each port is designed to connect to a single sub-device. In other words port aggregation is not currently supported. Changes since v2: - Rework Kconfig options and added COMPILE_TEST - Merged in provided vb2 buffer rework - Rebase on tip of lmm master and fixe vb2 split related changes Changes since v1: - Remove unnecessary format description - Reworked how transient frame format is maintained in order to make it easier to use the fill helper functions - Added a per port list of active frame format - Reworked an added missing vb2 cleanup code - Fix a module load/unload kernel oops - Switch to use proper int64 get function for pixel rate control ===== Here is a sample output of the v4l2-compliance tool: #
