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 [1] http://marc.info/?l=linux-omap&m=143752295508435&w=2 Suman Anna (4): ARM: dts: DRA7: Add dsp1_system syscon node ARM: dts: DRA74x: Add dsp2_system syscon node ARM: dts: DRA7: Add common IOMMU nodes ARM: dts: DRA74x: Add IOMMU nodes for DSP2 arch/arm/boot/dts/dra7.dtsi | 45 +++++++++++++++++++++++++++++++++++++++++++ arch/arm/boot/dts/dra74x.dtsi | 25 ++++++++++++++++++++++++ 2 files changed, 70 insertions(+) -- 2.4.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
