Janne Grunau	667b44ee3a	dt-bindings: iommu: apple,sart: Add apple,t8112-sart compatible string ... "apple,t8112-sart" as found on the Apple M2 SoC appears to be SART3 as well. To allow for later discovered incompatibilities use '"apple,t8112-sart", "apple,t6000-sart"' as compatible string.

Sven Peter	a12d521f4a	dt-bindings: iommu: Add Apple SART DMA address filter ... Apple SoCs such as the M1 come with a simple DMA address filter called SART. Unlike a real IOMMU no pagetables can be configured but instead DMA transactions can be allowed for up to 16 paddr regions. The consumer also needs special support since not all DMA allocations have to be added to this filter.
