How to find pin number or address for implementing GPIO Interrupt?

Hello.

I want to use GPIO Interrupt in imx6sx, especially using pad LCD1_DATA18 - GPIO3_IO19.

for implementing and testing Interrupt, it requires pin number or address, and irq number.

But I cant find its pin number or address even I read all datasheets and other Docs of imx6sx.

(Irq number of GPIO3_IO19 might be 103, right?)

I've never seen pin map or something like that..

so could you help me to solve this problem?

Best regards,

Jeehwan Kim

Hello Jeehwan,

    See imx6sxrm.pdf, please! 

    On page 199:

    The GPIO3_OI19's IRQ number is 103.  So you are right.

Have a nice day!
