There were already two versions of series to support SMMU for AP806,
including workaround for accessing ARM SMMU 64bit registers.
First [1] by Hanna Hawa and second [2] by Gregory CLEMENT.
Since it got stuck this is yet another try. I incorporated the V2 comments,
mainly by moving workaround code to arm-smmu-impl.c as requested.
For the record, AP-806 can't access SMMU registers with 64bit width,
this patches split the readq/writeq into two 32bit accesses instead
and update DT bindings.
The series was successfully tested on a vanilla v5.8-rc3 kernel and
Intel e1000e PCIe NIC. The same for platform devices like SATA and USB.

Do you have a v4 of this series? It looks like there were a few comments
left to address, but with that I can pick it up for 5.9.
Yes, I will send it out today.
Thanks,
Tomasz
