Documentation: dt: Update OMAP iommu bindings for DRA7 DSPs The DSP processor sub-systems on DRA7xx have two MMU instances each, one for the processor core and the other for an internal EDMA block. These MMUs need an additional shared register to be programmed in the DSP_SYSTEM sub-module to be enabled properly. The OMAP IOMMU bindings is updated to account for this additional syscon property required for these DSP IOMMU instances on DRA7xx SoCs. A new compatible "ti,dra7-dsp-iommu" is also defined to distinguish these devices specifically from other DRA7 IOMMU devices. An example of the DRA7 DSP IOMMU nodes is also added to the document for clarity. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
