Subject[PATCH 0/2] dmaengine: Support for IMG MDC
Date
This series adds support for the IMG Multi-threaded DMA Controller (MDC)
which is found on IMG SoCs. Currently this driver only supports the
variant found on the MIPS-based Pistachio SoC.

The MDC supports slave and memory-to-memory transfers on up to 32 channels.
Requests from channels are handled by MDC threads. Thread assignments are
per-channel and are specified in the device-tree.

Tested on a platform based on the Pistachio SoC with additional patches.
Support for Pistachio will be submitted later.

Based on Vinod's slave-dma/next. I can rebase on Maxime's device_control
refactoring [1] if necessary.
