Seen a lot of ARM&   TI OMAP discussions on this list.  I was
wondering if the DSPs on any devices that have ARM + DSP are
represented in the device trees yet.

So far, for the OMAP case, the DSP node is mostly empty.

The issue is that I'm not sure we can represent in the same DT both MPU and DSP view, since the DT root is supposed to represent a processor.
If we need the real DSP viewpoint, we will have to mostly duplicate the MPU view then remove MPU private peripherals and add the DSP private peripherals.

Is there pointer to an example dts that show whatever you have for DSP ?

Well this is really empty :-)

Extract from the arch/arm/dts/omap3.dtsi

	soc {
		compatible = "ti,omap-infra";
		mpu {
			compatible = "ti,omap3-mpu";
			ti,hwmods = "mpu";
		};

		iva {
			compatible = "ti,iva2.2";
			ti,hwmods = "iva";

			dsp {
				compatible = "ti,omap3-c64";
			};
		};
	};
