config WWAN
	tristate "WWAN Driver Core"
	help
	  Say Y here if you want to use the WWAN driver core. This driver
	  provides a common framework for WWAN drivers.

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

if WWAN

config WWAN_HWSIM
	tristate "Simulated WWAN device"
	help
	  This driver is a developer testing tool that can be used to test WWAN
	  framework.

	  To compile this driver as a module, choose M here: the module will be
	  called wwan_hwsim.  If unsure, say N.

config MHI_WWAN_CTRL
	tristate "MHI WWAN control driver for QCOM-based PCIe modems"
	depends on MHI_BUS
	help
	  MHI WWAN CTRL allows QCOM-based PCIe modems to expose different modem
	  control protocols/ports to userspace, including AT, MBIM, QMI, DIAG
	  and FIREHOSE. These protocols can be accessed directly from userspace
	  (e.g. AT commands) or via libraries/tools (e.g. libmbim, libqmi,
	  libqcdm...).

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

config MHI_WWAN_MBIM
        tristate "MHI WWAN MBIM network driver for QCOM-based PCIe modems"
        depends on MHI_BUS
        help
          MHI WWAN MBIM is a WWAN network driver for QCOM-based PCIe modems.
          It implements MBIM over MHI, for IP data aggregation and muxing.
          A default wwan0 network interface is created for MBIM data session
          ID 0. Additional links can be created via wwan rtnetlink type.

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

config QCOM_BAM_DMUX
	tristate "Qualcomm BAM-DMUX WWAN network driver"
	depends on (DMA_ENGINE && PM && QCOM_SMEM_STATE) || COMPILE_TEST
	help
	  The BAM Data Multiplexer provides access to the network data channels
	  of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm
	  MSM8916 or MSM8974. The connection can be established via QMI/AT from
	  userspace with control ports available through the WWAN subsystem
	  (CONFIG_RPMSG_WWAN_CTRL) or QRTR network sockets (CONFIG_QRTR).

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

config RPMSG_WWAN_CTRL
	tristate "RPMSG WWAN control driver"
	depends on RPMSG
	help
	  RPMSG WWAN CTRL allows modems available via RPMSG channels to expose
	  different modem protocols/ports to userspace, including AT and QMI.
	  These protocols can be accessed directly from userspace
	  (e.g. AT commands) or via libraries/tools (e.g. libqmi, libqcdm...).

	  This is mainly used for modems integrated into many Qualcomm SoCs,
	  e.g. for AT and QMI on Qualcomm MSM8916 or MSM8974. Note that many
	  newer Qualcomm SoCs (e.g. SDM845) still provide an AT port through
	  this driver but the QMI messages can only be sent through
	  QRTR network sockets (CONFIG_QRTR).

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

config IOSM
	tristate "IOSM Driver for Intel M.2 WWAN Device"
	depends on INTEL_IOMMU
	select NET_DEVLINK
	help
	  This driver enables Intel M.2 WWAN Device communication.

	  If you have one of those Intel M.2 WWAN Modules and wish to use it in
	  Linux say Y/M here.

	  If unsure, say N.
