Convert the Microchip PIC32 interrupt controller binding to schema format. It's a straight-forward conversion of the typical interrupt controller.

The Microchip PIC32 contains an Enhanced Vectored Interrupt Controller (EVIC).
|
|
It handles all internal and external interrupts. This controller exists
|
|
outside of the CPU and is the arbitrator of all interrupts (including
|
|
interrupts from the CPU itself) before they are presented to the CPU.
|
|
|
|
External interrupts have a software configurable edge polarity. Non external
|
|
interrupts have a type and polarity that is determined by the source of the
|
|
interrupt.
