Теперь по таймауту больше не вываливается, но может намертво повиснуть:
# capt -d /dev/video0 -o data.dat
Pb no camera found!!!

Откуда картинка, висит ведь :)
Я наконец то понял, чтобез драйвера (и I2C) ADV7180 эта штука работать не будет :), только не понял, Вы его сами добавляли?

либо драйвер ADV7180 к контексту плага адаптировать

Хотя драйвер и ругается, что не может найти камеру (добавления прерывания ничего не меняет)

The ISI module API is defined in drivers/media/video/atmel_isi.h and provides
following two functions for a camera driver.
int atmel_isi_register_camera(struct atmel_isi_camera *cam);
void atmel_isi_unregister_camera(struct atmel_isi_camera *cam);
The function atmel_isi_register_camera function can be called from a camera driver
to register itself. The atmel_isi_unregister_camera function removes the driver from
the ISI internal camera list. The parameter of both functions is a structure that needs
to be filled out from the camera driver. This structure looks as follows:
struct atmel_isi_camera {
const char *name;
struct module *owner;
struct list_head list;
unsigned int hsync_act_low:1;
unsigned int vsync_act_low:1;
unsigned int pclk_act_falling:1;
unsigned int has_emb_sync:1;
/* ISI supports up to 17 formats */
unsigned int pixelformats[17];
int (*get_format)(struct atmel_isi_camera *cam, struct atmel_isi_format *fmt);
int (*set_format)(struct atmel_isi_camera *cam, struct atmel_isi_format *fmt);
int (*start_capture)(struct atmel_isi_camera *cam);
int (*stop_capture)(struct atmel_isi_camera *cam);
struct atmel_isi *isi;
};
Fields that need to be filled out by the camera driver are.
• name: Name of the camera driver.
• hsync_act_low: Set to 1 if horizontal synchronization signal is active low. If active
high set it to 0.
• vsync_act_low: Set to 1 if vertical synchronization is active low. If not, set it to 0.
• pclk_act_falling: If the pixel data is valid at the falling edge of the pixel clock set it
to 1. Otherwise to 0.
• has_emb_sync: If the embedded synchronization mechanism is used, set it this
value to 1. If horizontal and vertical synchronization signals are used instead set
this value to 0.
In addition four functions must be implemented in the camera driver and the function
pointers in the above structure must be initialized to point to these functions. These
are functions that start/stop capturing (start_capture/stop_capture) and set/get the
camera video format (get_format/set_format). More functions may be implemented
later if more functionality of the V4L2 specification needs to be passed to the camera
driver.
