Hi Dave, Here is the series adding MHI client driver support to Qualcomm IPC router protocol. MHI is a newly added bus to kernel which is used to communicate to external modems over a physical interface like PCI-E. This driver is used to transfer the QMI messages between the host processor and external modems over the "IPCR" channel. For QRTR, this driver is just another driver acting as a transport layer like SMD. Currently this driver is needed to control the QCA6390 WLAN device from ath11k. The ath11k MHI controller driver will take care of booting up QCA6390 and bringing it to operating state. Later, this driver will be used to transfer QMI messages over the MHI-IPCR channel. The second patch of this series removes the ARCH_QCOM dependency for QRTR. This is needed because the QRTR driver will be used with x86 machines as well to talk to devices like QCA6390. Thanks, Mani Changes in v2: * Added cover letter * Removed casting of void pointer.
