Hello,

> This series adds support for integrating HDMA with the DWC EP driver.
> 
> Hyper DMA (HDMA) is already supported by the dw-edma dmaengine driver.
> Unlike it's predecessor Embedded DMA (eDMA), HDMA supports only unroll
> mapping format and doesn't support auto detecting the read/write channels.
> 
> Hence, this series modifies the existing eDMA code to work with HDMA by
> honoring the platform supplied mapping format and read/write channels
> count.
> 
> The platform drivers making use of HDMA should pass the EDMA_MF_HDMA_NATIVE
> flag and provide channels count. In this series, HDMA support is added for
> the Qcom SA8775P SoC and the DMA support in enabled in MHI EPF driver as
> well.
