Move the PCI 'interrupt-map-mask' and '#interrupt-cells' properties alongside the 'interrupt-map' property in each board dts. This avoids having incomplete set of interrupt properties which may fail validation. Cc: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Rob Herring <robh@kernel.org>
