[PATCH 0/3] Request direct mapping for modem firmware subdevice

[Sibi Sankar]

The Q6 modem sub-system has direct access to DDR through memnoc and
an indirect access routed through a SMMU which MSS CE (crypto engine
sub-component of MSS) uses during out of reset sequence. Request direct
mapping for the modem-firmware subdevice since smmu is not expected
to provide access control/translation for these SIDs (sandboxing of the
modem is achieved through XPUs engaged using SMC calls).

Sibi Sankar (3):
  iommu: Export "iommu_request_dm_for_dev"
  dt-bindings: remoteproc: qcom: Add modem-firmware bindings
  remoteproc: qcom_q6v5_mss: Request direct mapping for firmware
    subdevice
