This is a generic MHI-over-PCI controller driver for MHI only devices such as QCOM modems. For now it supports registering of Qualcomm SDX55 based PCIe modules. The MHI channels have been extracted from mhi downstream driver. This driver is for MHI-only devices which have all functionalities exposed through MHI channels and accessed by the corresponding MHI device drivers (no out-of-band communication).
