Hi,
I took a quick look at the code, The Xilinx implements mmu-500 which is a SMMU- 
v2.
I am not very familiar with V2, however, the architecture and internal workings 
are different between v2 and v3. 
hence there are 2 different drivers in Linux for V2 and V3, and the code I 
posted is for SMMU-v3.

Cheers,
