Hi,
SM6350 has a SMMUv2-compatible(-ish, obviously) instance that
is responsible for working with Adreno and its GMU.
Recently, it was decided that there is no point in adding more
mmu-500 compatibles to the driver, however after chatting with
Dmitry on IRC, it was concluded that it's okay to add that for v2, as
these older implementations can vary so much from SoC to SoC that
having a common compatible is really not feasible..

Oh, I forgot to mention this patch was made on top of Dmitry's work. But
it's good that you pointed that out!
