font-family:Arial'>I am trying to write a device driver that uses an external
interrupt (one of the 16 irq lines) for the Freescale P1020 processor and I
hope some of you can help. Am I suppose to setup a separate node in the
dts and look for that node in my driver to setup the interrupt? Or does
the dts interrupt declaration belong to the interrupt-controller declaration? I
noticed the mpc8xxx_gpio driver defined its own irq_chip but I thought that may
be because each gpio pin can trigger an interrupt. Do I need to define my
own irq_chip structure for my device even if I am using one of the hard irq
lines? <o:p></o:p></span></font></p>
