The R_INTC interrupt controller handles the NMI interrupt pin for the SoC. While there is no documentation or code from the vendor for this device on the A83T, existing mainline kernel drivers and bindings show this to be similar to the old Allwinner interrupt controller found on the A10 SoC, but with only the NMI interrupt wired. Register poking experiments confirm this. The device seems to be the same across all recent Allwinner SoCs, apart from the A20 and A80, which have a separate set of registers to handle the NMI interrupt. We already have a set of bindings supporting this on the A31. Add a device node for it, with an SoC specific compatible.
