Detailed Description

A DMA channel interrupt callback and the context passed to it.

Set via PHAL_DMA_initWithCallback(). Leave zero-initialized (irq_fn == nullptr) for channels that don't need interrupt-driven completion (ex: a channel whose completion is polled or driven by another peripheral's IDLE/status interrupt instead).
