Following the feedback i got from:

I have written a driver (.c file) by comparing it with an existing driver
and "borrowing" heavily from its code.

The driver is registered fine and init() and probe() are working fine.
I am also able to access the peripheral device registers. :-)

However i am a bit hazy about the IRQ/ISR.
The peripheral-device is a input device and raises an interrupt on a GPIO pin.

How do i move ahead from my current state ( init(), probe(), etc. )
to be able to handle the IRQ and execute my ISR function??

Many-Thanks in Advance

How CPU finds ISR and distinguishes between devices

as seen on Stack Overflow - Search for 'Stack Overflow'
I should first share all what I know - and that is complete chaos. There are several different questions on the topic, so please don't get irritated :). 1) To find an ISR, CPU is provided with a interrupt number. In x86 machines (286/386 and above) there is a IVT with ISRs in it; each entry of 4… >>> More
