Where is the > call(s) from/to > interrupt handlers? Or is this just a future extension? We use the SPI communication inside another device driver (for CAN bus). It is this other driver that will call the SPI I/O function in it's interrupt handler. > I would like to keep the interrupts on, if possible. Feel free to modify the driver according to your needs. It should not be a problem except for special cases like ours.
