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. > > Testing > ------- > > Tested on Qualcomm SA8775P Ride board. > > Dependency > ---------- > > Depends on: > https://lore.kernel.org/dmaengine/20240129-b4-feature_hdma_mainline-v7-0-8e8c1acb7a46@xxxxxxxxxxx/ > https://lore.kernel.org/all/1701432377-16899-1-git-send-email-quic_msarkar@xxxxxxxxxxx/ > > NOTE: I've taken over this series from Mrinmay who posted v1: > https://lore.kernel.org/linux-pci/1705669223-5655-1-git-send-email-quic_msarkar@xxxxxxxxxxx/ Applied to qcom, thank you!
