With INTEL_IOMMU disable config or by forcing intel_iommu=off from
grub some of the features of IOSM driver like browsing, flashing &
coredump collection is not working.
When driver calls DMA API - dma_map_single() for tx transfers. It is
resulting in dma mapping error.
Set the device DMA addressing capabilities using dma_set_mask() and
remove the INTEL_IOMMU dependency in kconfig so that driver follows
the platform config either INTEL_IOMMU enable or disable.

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).
