Add nodes required for communication through the Tegra Combined UART. This includes the AON HSP instance, addition of shared interrupts for the TOP0 HSP instance, and finally the TCU node itself. Also mark the HSP instances as compatible to tegra194-hsp, as the hardware is not identical but is compatible to tegra186-hsp.

I might be wrong, but I think we may need to update the binding doc compatibility property for hsp. For example see 'Documentation/devicetree/bindings/arm/tegra/nvidia,tegra20-flowctrl.txt'. Cheers Jon -- nvpublic
