iommu/ipmmu-vmsa: IPMMU slave device whitelist [PATCH/RFC 1/2] arm64: mm: Silently allow devices lacking IOMMU group [PATCH/RFC 2/2] iommu/ipmmu-vmsa: Opt-in slave devices based on ES version
Here's a little prototype that shows how DT integration of IPMMU details may be integrated and merged upstream based on SoC data sheet ahead of time followed by enablement in the IPMMU driver code once the appropriate SoC ES version has been released and the hardware has been tested.
