Connecting RGB888 format camera device to TX2

hello sumisumisumi,

we don’t support RGB888 by default,
please refer to /kernel_src/kernel/kernel-4.4/include/uapi/linux/videodev2.h
you might have a try to configure it as below.

#define V4L2_PIX_FMT_RGB24   v4l2_fourcc('R', 'G', 'B', '3') /* 24  RGB-8-8-8     */

you should also extend the supported pixel formats as below.
/kernel/kernel-4.4/drivers/media/platform/tegra/camera/sensor_common.c

static int extract_pixel_format(const char *pixel_t, u32 *format)
{
...
}

/kernel/kernel-4.4/drivers/media/platform/tegra/camera/camera_common.c

static const struct camera_common_colorfmt camera_common_color_fmts[] = {
...
}
