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 <linux/clk.h> +-#include <linux/delay.h> +-#include <linux/device.h> +-#include <linux/dma-mapping.h> +-#include <linux/err.h> +-#include <linux/init.h> +-#include <linux/interrupt.h> +-#include <linux/io.h> +-#include <linux/module.h> +-#include <linux/of_device.h> +-#include <linux/of_graph.h> +-#include <linux/pinctrl/consumer.h> +-#include <linux/platform_device.h> +-#include <linux/pm_runtime.h> +-#include <linux/slab.h> +-#include <linux/uaccess.h> +-#include <linux/videodev2.h> +- +-#include <media/v4l2-common.h> +-#include <media/v4l2-ctrls.h> +-#include <media/v4l2-dev.h> +-#include <media/v4l2-device.h> +-#include <media/v4l2-dv-timings.h> +-#include <media/v4l2-event.h> +-#include <media/v4l2-ioctl.h> +-#include <media/v4l2-fwnode.h> +-#include <media/videobuf2-dma-contig.h> +- +-#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.
