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 <bparrot@ti.com> --- drivers/media/platform/Kconfig | 12 + drivers/media/platform/Makefile | 2 + drivers/media/platform/ti-vpe/Makefile | 4 + drivers/media/platform/ti-vpe/cal.c | 2161 ++++++++++++++++++++++++++++++ drivers/media/platform/ti-vpe/cal_regs.h | 779 +++++++++++ 5 files changed, 2958 insertions(+) create mode 100644 drivers/media/platform/ti-vpe/cal.c create mode 100644 drivers/media/platform/ti-vpe/cal_regs.h
