Unicam receives CSI-2 or -- * CCP2 data and writes it into SDRAM. -- * The only potential processing options are to repack Bayer data into an -- * alternate format, and applying windowing. -- * The repacking does not shift the data, so can repack V4L2_PIX_FMT_Sxxxx10P -- * to V4L2_PIX_FMT_Sxxxx10, or V4L2_PIX_FMT_Sxxxx12P to V4L2_PIX_FMT_Sxxxx12, -- * but not generically up to V4L2_PIX_FMT_Sxxxx16. The driver will add both -- * formats where the relevant formats are defined, and will automatically -- * configure the repacking as required. -- * Support for windowing may be added later. -- * -- * It should be possible to connect this driver to any sensor with a -- * suitable output interface and V4L2 subdevice driver. -- * -- * bcm2835-camera uses the VideoCore firmware to control the sensor, -- * Unicam, ISP, and all tuner control loops. Fully processed frames are -- * delivered to the driver by the firmware. It only has sensor drivers -- * for Omnivision OV5647, and Sony IMX219 sensors. -- * -- * The two drivers are mutually exclusive for the same Unicam instance. -- * The VideoCore firmware checks the device tree configuration during boot. -- * If it finds device tree nodes called csi0 or csi1 it will block the -- * firmware from accessing the peripheral, and bcm2835-camera will -- * not be able to stream data. -- */ -- --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include --#include -- --#include --#include --#include --#include --#include --#include --#include --#include --#include -- --#include "vc4-regs-unicam.h" -- --#define UNICAM_MODULE_NAME "unicam" --#define UNICAM_VERSION "0.1.0" -- --static int debug; --module_param(debug, int, 0644); --MODULE_PARM_DESC(debug, "Debug level 0-3"); -- --#define unicam_dbg(level, dev, fmt, arg...) \ -- v4l2_dbg(level, debug, &(dev)->v4l2_dev, fmt, ##arg) --#define unicam_info(dev, fmt, arg...) \ -- v4l2_info(&(dev)->v4l2_dev, fmt, ##arg) --#define unicam_err(dev, fmt, arg...) \ -- v4l2_err(&(dev)->v4l2_dev, fmt, ##arg) -- --/* To protect against a dodgy sensor driver never returning an error from -- * enum_mbus_code, set a maximum index value to be used. -- */ --#define MAX_ENUM_MBUS_CODE 128 -- --/* -- * Stride is a 16 bit register, but also has to be a multiple of 32. -- */ --#define BPL_ALIGNMENT 32 --#define MAX_BYTESPERLINE ((1 << 16) - BPL_ALIGNMENT) --/* -- * Max width is therefore determined by the max stride divided by -- * the number of bits per pixel.
