This module is responsible for communicating WLAN control messages to FW over QMI interface. This patch series enables the qmi handshakes required for WCN3990 chipset. QUALCOMM MSM 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 framework https://lwn.net/Articles/729924/. Below is the sequence of qmi handshake. QMI CLIENT(APPS) QMI SERVER(FW in Q6) <------wlan service discoverd---- -----connect to wlam qmi service-----> ------------wlan info request-----> <------------wlan info resp------------ ------------msa info req--------> <------------msa info resp------------ ------------msa ready req--------> <------------msa ready resp------------ <------------msa ready indication------- ------------capability req-------> <------------capability resp------------ ------------qmi bdf req---------> <------------qmi bdf resp------------ ------------qmi cal trigger-------> <------------ QMI FW ready indication------- WLAN fw is running in modem Q6 dsp as user PD(protection domain). Sequence of user PD loading is as following. 1) Remote proc PIL driver loads the modem fw/ROOT PD. 2) As part of ROOT pd boot-up it queries to a daemon(pd_mapper) running in apps processor to determine how many usre pd's to be loaded by the remote processor(Q6). 3) Once user pd info is known to remote processor it loads the user pd via tftp protocol. https://github.com/andersson/pd-mapper https://github.com/andersson/tqftpserv Changes since V3: Removed msa memory child node and used only memory-region property. Fixed sparse warning reported in v3 change. Changed qmi board id data type to u32 to align with fw defined value. Changes since V2: Addressed review comments from v2 version. Removed msa-size from dt binding and added reference to reserved-memory/reserved-memory.txt. Changes since V1: Removed qmi client driver and integrated qmi client handshakes in snoc platform driver. Addressed comments on v1 version. Switched to ath10k bdf download infra(board-2.bin) Added MSA fixed region support to support unload use-case. Unified logging. Testing: Tested all qmi handshakes, driver load/unload and STA/SAP sanity testing.
