0x2184 is a secure SID. I think qcm6490-fairphone-fp5.dts needs to override the
iommus property as well to retain only the non secure SID i.e 0x2180 ? I am
seeing below crash

Could you please reconfirm if Video SID 0x2184 (and mask) is allowed by the
qcm6490-fairphone-fp5 hardware having TZ ?

I tested on SC7280 (herobrine) and all good.
