[PATCHv2 3/4] ARM: dts: OMAP4: Add IOMMU nodes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Florian Vaussard <florian.vaussard@xxxxxxx>

Add the IOMMU nodes for the DSP and IPU subsystems. The MMU
within the IPU sub-system also supports a bus error back
capability, not available on the DSP MMU.
