dt-bindings: memory: tegra: Add Tegra264 support

2025-07-11T14:48:06+00:00

Add bindings for the Memory Controller (MC) and External Memory Controller (EMC) found on the Tegra264 SoC. Tegra264 SoC has a different number of interrupt lines for MC sub-units: UCF_SOC, hub, hub common, syncpoint and MC channel. The total number of interrupt lines is eight. Update maxItems for MC interrupts accordingly. This also adds a header containing the memory client ID definitions that are used by the interconnects property in DT and the tegra_mc_client table in the MC driver. These IDs are defined by the hardware, so the numbering doesn't start at 0 and contains holes. Also added are the stream IDs for various hardware blocks found on Tegra264. These are allocated as blocks of 256 IDs and each block can be subdivided for additional fine-grained isolation if needed.

dt-bindings: mediatek: mt8188: Add binding for MM & INFRA IOMMU

2023-08-07T12:15:45+00:00

Add descriptions for mt8188 IOMMU which also use ARM Short-Descriptor translation table format. In mt8188, there are two smi-common HW and IOMMU, one is for vdo(video output), the other is for vpp(video processing pipe). They connects with different smi-larbs, then some setting(larbid_remap) is different. Differentiate them with the compatible string. Something like this: IOMMU(VDO) IOMMU(VPP) | | SMI_COMMON_VDO SMI_COMMON_VPP --------------- ---------------- | | ... | | ... larb0 larb2 ... larb1 larb3 ... We also have an IOMMU that is for infra master like PCIe. And infra master don't have the larb and ports.
