Hello,
I looked up the code of smmu.c and the manual of smmu v3. For the suspend is
implemented
by the external clock-gating, it is not clear wh
Add suspend and resume support for arm-smmu-v3 by low-power mode.
When the smmu is suspended, it is powered off and the registers are
cleared. So saves the msi_msg context during msi interrupt initialization
of smmu. When resume happens it calls arm_smmu_device_reset() to restore
the registers.
