Drenesas,ipmmu-vmsa.txt1 * Renesas VMSA-Compatible IOMMU
3 The IPMMU is an IOMMU implementation compatible with the ARM VMSA page tables.
5 connected to the IPMMU through a port called micro-TLB.
10 - compatible: Must contain SoC-specific and generic entry below in case
11 the device is compatible with the R-Car Gen2 VMSA-compatible IPMMU.
13 - "renesas,ipmmu-r8a73a4" for the R8A73A4 (R-Mobile APE6) IPMMU.
14 - "renesas,ipmmu-r8a7743" for the R8A7743 (RZ/G1M) IPMMU.
15 - "renesas,ipmmu-r8a7745" for the R8A7745 (RZ/G1E) IPMMU.
16 - "renesas,ipmmu-r8a7790" for the R8A7790 (R-Car H2) IPMMU.
17 - "renesas,ipmmu-r8a7791" for the R8A7791 (R-Car M2-W) IPMMU.
