We are trying to access external interrupt IRQ0 to IRQ11 using Linux. What is the configuration required in uboot/DTS/Linux to test the external interrupts?
The given solution is for layerscape processors. The same wont be applicable for Powerpc based processor.
It has information about how to manage the interrupts in linux (any device), the configuration of the external IRQ's is available in the RM (Polarity, Sense, Priority, etc.)
