[PATCH 0/7] Improvements to Qcom PCIe EP and EPF MHI drivers

From: Manivannan Sadhasivam
Date: Tue Jun 06 2023 - 07:58:38 EST


Hi,

This series adds eDMA (embedded DMA) support to the Qcom PCIe EP and EPF
MHI drivers for offloading the transfers between PCIe bus and the EP
memory. eDMA support makes use of the recently merged eDMA DMAEngine driver
and its integration with DWC PCIe EP core [1].

This series also adds Qcom SM8450 SoC support to EPF MHI driver that has
the eDMA support built-in.
