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.
