Changes in v4: * Restore the arm_smmu_suspend() function code to the v2 version(Directly return 0 in it).
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 what the SMMUv3 needs to do. Is it the same as that in smmu.c? I roll back the code here, and hope to get some advice.
