	Recent Linux kernel versions have introduced a generic WWAN subsystem that provides various char devices for QMI, AT etc, similar to the subsystem-specific char devices for USB or RPMSG. The RPMSG char device for Qualcomm SoCs (e.g. MSM8916/MSM8974) are particularly complicated to work with because they need to be explicitly created from userspace with rpmsgexport and don't show up automatically. However, it turns out it's fairly simple to wrap the RPMSG subsystem in a simple driver for the WWAN subsystem. This has several advantages: - We can drop support for the special RPMSG char devices entirely at some point. - The WWAN char devices show up automatically, without having to export them explicitly, making ModemManager work out of the box on these devices. For now, just support using the WWAN subsystem alternatively for the qcom-soc plugin. Later we can consider dropping the old RPMSG code.

2020-11-20	qcom-soc: new plugin for Qualcomm SoCs	Aleksander Morgado
	This plugin implements support for old Qualcomm SoCs like the MSM8916 or the MSM8974, where: * control ports are available via RPMSG channels exported as devices e.g. with rpmsgexport: https://github.com/andersson/rpmsgexport * network ports are exposed by the bam-dmux kernel driver: https://github.com/msm8916-mainline/linux/commits/bam-dmux Adding support for newer Qualcomm SoCs (e.g. QRTR+IPA) could be done in a similar way on this very same plugin. This plugin is the first and only one that implements support for a modem device that is "built in" the system, as opposed to external modems that may be available via USB or PCI. The ID_MM_PHYSDEV_UID based udev tags provided by the plugin provide the logic to bind all the SoC ports together in the same modem object, and therefore ID_MM_PHYSDEV_UID should not be used by users to override the ones set by the plugin. All "rpmsg[0-9]" ports that are considered part of the modem are flagged as candidate, ignoring the parent "rpmsg_ctrl[0-9]" ports on purpose. This setup therefore assumes that the channels have been exported already as devices (e.g. using rpmsgexport). libqmi 1.27.2 is required to support the "WDS Bind Data Port" message.
