[ts-7000] Re: Interrupt Controller

["ElianeMazzawi" <>]

I am having trouble finding how to write the device driver for using 
gpio interrupts on portA and portB. i was hoping someone could tell 
me if i am correct at how this would work:

we enable interrupts of some portA pins by writing some 1's on 
GPIOIntEn, and setup up the GPIOIntType1 and GPIOIntType2

so now when some pin on portA goes high, it causes an interrupt that 
goes to the Vectored Interrupt Controller, which causes the IRQ to 
go high, and when that happens we need to write some C code so that 
linux will acknowledge the IRQ, read the VICxIRQStatus, if it has a 
value of 59 then it was a GPIO portA or B interrupt and it will do 
whatever ISR we tell it to do?

any help at all will be appreciate, tia.
