                   Thulium v1.  You *must* also set qcom,tz-device-id for
                   this to work.
 
-- qcom,no-mmu-enable : When attaching to this SMMU, program everything as
-                  usual (stream matching table, etc) but leave the SCTLR.M
-                  bit disabled, so that the SMMU doesn't actually perform
-                  translations.  This is needed in cases where the stream
-                  matching table needs to be set up without turning on SMMU
-                  translations (for example, when nested translations are
-                  used with a hypervisor controlling stage-2).  This mode of
-                  operation is described in the ARM SMMU spec as "stage 1
-                  and stage 2 contexts are valid, but the SMMU is not
-                  enabled for stage 1 translation" (Section 2.1: "Overview
-                  of SMMU operation").

 - qcom,no-smr-check : Usually when an SMMU probes we do a sanity check on
                   the SMR registers to make sure they can fully support all
                   of the mask bits.  This check can cause problems for use
