Are device drivers available for the PL330?

Applies to: PL330 AXI DMA Controller

Answer

No, ARM does not provide device drivers for the DMAC (PL330).

For embedded applications, it is desirable that a device driver uses minimal amounts of memory. An ARM generic driver, that controls all of the configurable features of the DMAC, would be inefficient in its use of memory.

ARM therefore recommends that you create your own device driver so that it is specific to your configuration of the controller.
