This patchset introduces support for MediaTek High-Speed DMA controller (MTK-HSDMA) Currently, the driver is already tested successfully with dmatest module on MT7622 and MT7623 SoC. MTK-HSDMA on MT7622/23 SoC has a single ring which is dedicated for doing memory-to-memory transfer through ring-based descriptor management. Even though there is only a single ring available inside HSDMA, the driver is being extended to the support for multiple virtual channels processing simultaneously by means of DMA_VIRTUAL_CHANNELS.
