Is it really necessary to have all this in the device tree? You know from the compatible that this is "renesas,sh7751-intc" and I bet this table will be the same for any sh7751 right? Then just put it in a table in the driver instead and skip this from the device tree and bindings. If more interrupt controllers need to be supported by the driver, you can simply look up the table from the compatible string. Yours, Linus Walleij
