but mediatek jpeg enc/dec driver still is 32bit,
This is obvious by the mere fact that you send a patch so this part can
be omitted.
then need to set the bit32/bit33 iova to jpeg HW.
My suggestion for the whole commit message:
The HW iommu is able to support a 34-bit iova address-space (16GB),
enable this feature for the encoder/decoder driver by shifting the
address by two bits and setting the extended address registers.

No, I don't like mixing a new feature to the core of the driver with
adding support for a new variant, do that in a different patch series.
(Meaning do not add it as an extra patch either, send a separate series
with that change as it is totally unrelated to the change you do here)
