Handling interrupts in spidev

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
          I am using a custom ARM board. I have a SPI slave device and using the spidev_test utility I am able to do ioctls on the slave device.
However, I have a problem. The SPI slave device has an interrupt pin and I want to process the interrupt and send some data into the userspace when I receive the interrupt. Can anybody please suggest me a way to do this using spidev driver?

Regards,
Amit.
