This change introduces initial support for a WWAN framework. Given the complexity and heterogeneity of existing WWAN hardwares and interfaces, there is no strict definition of what a WWAN device is and how it should be represented. It's often a collection of multiple devices that perform the global WWAN feature (netdev, tty, chardev, etc). One usual way to expose modem controls and configuration is via high level protocols such as the well known AT command protocol, MBIM or QMI. The USB modems started to expose them as character devices, and user daemons such as ModemManager learnt to use them. This initial version adds the concept of WWAN port, which is a logical pipe to a modem control protocol. The protocols are rawly exposed to user via character device, allowing straigthforward support in existing tools (ModemManager, ofono...). The WWAN core takes care of the generic part, including character device management, and relies on port driver operations to receive/submit protocol data. Since the different devices exposing protocols for a same WWAN hardware do not necessarily know about each others (e.g. two different USB interfaces, PCI/MHI channel devices...) and can be created/removed in different orders, the WWAN core ensures that all WAN ports contributing to the 'whole' WWAN feature are grouped under the same virtual WWAN device, relying on the provided parent device (e.g. mhi controller, USB device). It's a 'trick' I copied from Johannes's earlier WWAN subsystem proposal. This initial version is purposely minimalist, it's essentially moving the generic part of the previously proposed mhi_wwan_ctrl driver inside a common WWAN framework, but the implementation is open and flexible enough to allow extension for further drivers.
