Subject: [Patch v3 0/2] media: v4l: 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.
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
