Hi all:
This patchset introduces the Loongson multi-channel DMA controller,
which is present in the Loongson-2K0300 and Loongson-2K3000 processors.
It is a multi-channel controller that enables data transfers from memory
to memory, device to memory, and memory to device, as well as channel
prioritization configurable through the channel configuration registers.
Additionally, since multiple distinct types of DMA controllers exist on
the Loongson platform, I have attempted to consolidate all Loongson DMA
drivers into a new directory named `Loongson` for easier management.
Thanks.
Binbin
