-- * BCM2835 Unicam Capture Driver
-- *
-- * Copyright (C) 2017-2020 - Raspberry Pi (Trading) Ltd.
-- *
-- * Dave Stevenson <dave.stevenson@raspberrypi.com>
-- *
-- * Based on TI am437x driver by
-- * Benoit Parrot <bparrot@ti.com>
-- * Lad, Prabhakar <prabhakar.csengg@gmail.com>
-- *
-- * and TI CAL camera interface driver by
-- * Benoit Parrot <bparrot@ti.com>
-- *
-- *
-- * There are two camera drivers in the kernel for BCM283x - this one
-- * and bcm2835-camera (currently in staging).
-- *
-- * This driver directly controls the Unicam peripheral - there is no
-- * involvement with the VideoCore firmware. 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.
