iMX28 Linux Device Tree - Configure Pin for External Interrupt

Question asked by Ryan Bryngelson on Apr 15, 2013

Can anyone help me define a device tree node that configures a GPIO pin to generate an interrupt?  I have a device that asserts an IRQ and would like to handle it in the kernel.  I'm attempting to use MX28_PAD_GPMI_D04__GPIO_0_4 for the IRQ pin.  I'm also using a mainline 3.8.3 kernel.

 

Thanks,

Ryan
