Thanks for the suggestions, I was unsure what to use for the sizes. The reg field is unused by the upstream driver so it is hard to figure out.
However, I'm not sure about some of your suggestions for the base address. For example, for "mc_virt" you suggest 0x0163d000, and I have 0x09100000. In the downstream dts, "mc_virt-base" is 0x9100000 and qcom,base-offset for fab_mc_virt is 0. Do you have an explanation for why your suggestion is so different?
