Timer subdevice.

#define A4L_SUBD_MEMORY   (A4L_SUBD_MASK_SPECIAL|0x100)

Memory, EEPROM, DPRAM.

#define A4L_SUBD_CALIB   (A4L_SUBD_MASK_SPECIAL|0x200)

Subdevice features

Flags to define the subdevice's capabilities

#define A4L_SUBD_CMD   0x1000

The subdevice can handle command (i.e it can perform asynchronous acquisition).

#define A4L_SUBD_MMAP   0x8000

The subdevice support mmap operations (technically, any driver can do it; however, the developer might want that his driver must be accessed through read / write.
