Do ARM supply a Linux reference driver for PL330?

Applies to: PL330 AXI DMA Controller

Answer

ARM do not supply any reference drivers for PL330.

PL330 is highly configurable and it would be impractical to supply a
large driver for all configurations. We expect customers to write
optimised driver code for their own specific implementations.

Attempts have been made in the past to develop such a driver but it was
quickly realised that this was impractical due to the complexity of the
device and the range of possible configurations.
