2021-12-09net: wwan: iosm: fixes unable to send AT command during mbim txM Chetan Kumar
ev_cdev_write_pending flag is preventing a TX message post for AT port while MBIM transfer is ongoing. Removed the unnecessary check around control port TX transfer.

2021-12-09net: wwan: iosm: fixes net interface nonfunctional after fw flashM Chetan Kumar
Devlink initialization flow was overwriting the IP traffic channel configuration. This was causing wwan0 network interface to be unusable after fw flash. When device boots to fully functional mode restore the IP channel configuration.

In TX packet accumulation flow transport layer is giving a doorbell to device even though there is no pending control TX transfer that needs immediate attention. Introduced a new hpda_ctrl_pending variable to keep track of pending control TX transfer. If there is a pending control TX transfer which needs an immediate attention only then give a doorbell to device.

On early detection of device in boot rom stage. Driver registers with Devlink framework and establish transport channel for PSI (Primary Signed Image) injection. Once PSI is injected to device, the device execution stage details are read to determine whether device is in flash or exception mode. The collected information is reported to devlink user space application & based on this informationi, application proceeds with either modem firmware flashing or coredump collection.

2021-08-04net: wwan: Add MHI MBIM network driverLoic Poulain
Add new wwan driver for MBIM over MHI. MBIM is a transport protocol for IP packets, allowing packet aggregation and muxing. Initially designed for USB bus, it is also exposed through MHI bus for QCOM based PCIe wwan modems. This driver supports the new wwan rtnetlink interface for multi-link management and has been tested with Quectel EM120R-GL M2 module.

2021-07-23wwan: core: Fix missing RTM_NEWLINK event for default linkLoic Poulain
A wwan link created via the wwan_create_default_link procedure is never notified to the user (RTM_NEWLINK), causing issues with user tools relying on such event to track network links (NetworkManager). This is because the procedure misses a call to rtnl_configure_link(), which sets the link as initialized and notifies the new link (cf proper usage in __rtnl_newlink()).

2021-06-22wwan: core: add WWAN common private data for netdevSergey Ryazanov
The WWAN core not only multiplex the netdev configuration data, but process it too, and needs some space to store its private data associated with the netdev. Add a structure to keep common WWAN core data. The structure will be stored inside the netdev private data before WWAN driver private data and have a field to make it easier to access the driver data. Also add a helper function that simplifies drivers access to their data. At the moment we use the common WWAN private data to store the WWAN data link (channel) id at the time the link is created, and report it back to user using the .fill_info() RTNL callback. This should help the user to be aware which network interface is bound to which WWAN device data channel.
