This patchset introduces support for MediaTek Command-Queue DMA controller.
MediaTek Command-Queue DMA controller (CQDMA) on MT6765 SoC is dedicated to memory-to-memory transfer through queue-based descriptor management.
There are only 3 physical channels inside CQDMA, while the driver is extended to support 32 virtual channels for multiple dma users to issue dma requests onto the CQDMA simultaneously.
