[ad7791.c]Question about irq in ad7791_probe()

Paul.Wang on Apr 15, 2015

Base on below link, we have a question about ad7791.c.

http://wiki.analog.com/resources/tools-software/linux-drivers/iio-adc/ad7791

Inside ad7791_probe(), we would like to know whether irq is transmit through SPI interface? Or a dedicate pin from AD7791 chip to CPU general purpose input pin? Thank you.

Kindly regards

Paul.Wang

Hi,

Typically that is a separate pin on the SoC that is connected in addition to the MISO signal the same DOUT/RDY pin of the AD7791.
