0011 Say Y here if you want to use the WWAN driver core. This driver
0012 provides a common framework for WWAN drivers.

0014 To compile this driver as a module, choose M here: the module will be
0015 called wwan.

0026 If this option is selected, then you can find the debug interface
0027 elements for each WWAN device in a directory that is corresponding to
0028 the device name: debugfs/wwan/wwanX.

0043 MHI WWAN CTRL allows QCOM-based PCIe modems to expose different modem
0044 control protocols/ports to userspace, including AT, MBIM, QMI, DIAG
0045 and FIREHOSE. These protocols can be accessed directly from userspace
0046 (e.g. AT commands) or via libraries/tools (e.g. libmbim, libqmi,

0056 MHI WWAN MBIM is a WWAN network driver for QCOM-based PCIe modems.
0057 It implements MBIM over MHI, for IP data aggregation and muxing.
0058 A default wwan0 network interface is created for MBIM data session
0059 ID 0. Additional links can be created via wwan rtnetlink type.

0068 The BAM Data Multiplexer provides access to the network data channels
0069 of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm
0070 MSM8916 or MSM8974. The connection can be established via QMI/AT from
0071 userspace with control ports available through the WWAN subsystem
0072 (CONFIG_RPMSG_WWAN_CTRL) or QRTR network sockets (CONFIG_QRTR).

0080 help
0081 RPMSG WWAN CTRL allows modems available via RPMSG channels to expose
0082 different modem protocols/ports to userspace, including AT and QMI.
0083 These protocols can be accessed directly from userspace
0084 (e.g. AT commands) or via libraries/tools (e.g. libqmi, libqcdm...).
0085
0086 This is mainly used for modems integrated into many Qualcomm SoCs,
0087 e.g. for AT and QMI on Qualcomm MSM8916 or MSM8974. Note that many
0088 newer Qualcomm SoCs (e.g. SDM845) still provide an AT port through
0089 this driver but the QMI messages can only be sent through
0090 QRTR network sockets (CONFIG_QRTR).
