SDM845's Adreno SMMU is unique in that it actually advertizes support
for 16K (and 32M) pages, which doesn't hold for newer SoCs.
My question is about forbidding 16k pages for sdm845 only or for other
chips too. I'd assume that it shouldn't also work for other smmu-v2
platforms.
Yes, my understanding was that SMMUv2 based IPs doesn't have 16k support
and it is only starting from SMMUv3.
