[PATCH 0/4] Add DRA7 IOMMU DT nodes

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

 



Hi Tony,

The following patches add the basic DT nodes for the DSP
and IPU IOMMU devices for the DRA7xx SoC family. The first
two patches add syscon nodes for DSP_SYSTEM sub-modules, while
the last two add the IOMMU nodes.

The IPU IOMMU nodes mostly are similar to existing ones on OMAP4
and OMAP5. The DSP sub-system though has two MMUs, with a dedicated
MMU for the internal EDMA engine. On previous SoCs, a single MMU
served both the DSP processor and the internal EDMA. The DSP IOMMU
nodes require a new property to reference the syscon nodes, as they
each need a specific bit to be set in a register within the
corresponding DSP_SYSTEM sub-module. So, these are pending based
on the equivalent bindings update series [1]. Please let me know
if the binding looks ok to you, as this seems it can be done in
couple of ways.

Patches are based on 4.2-rc3.

regards
Suman
