Cover letter [PATCH v3 00/12] *** Add support for wifi QMI client driver ***
Add QMI client driver for Q6 integrated WLAN connectivity subsystem. This module is responsible for communicating WLAN control messages to FW over QMI interface.
“QUALCOMM Messaging Interface”(QMI) provides the control interface between components running b/w remote processors with underlying transport layer based on integrated chipset(shared memory) or discrete chipset(PCI/USB/SDIO/UART).
QMI client driver implementation is based on qmi frmework https://lwn.net/Articles/729924/.
Below is the sequence of qmi handshake.
