Hello all,  
I want to define a gpio interrupt signal to manage the spi\_srdy mechanism, however I am a little bit confised with the GPIO kernels and user space GPIO mapping signal. So I intend to use tha GPIO36 as an interrupt signal. However I cannot figure which value should I use with the gpio\_request function. Can you help me with this issue. Thank you.
