It's understood that the AB8500 should be subordinate to the DB8500; however, the AB8500 uses the GIC as it's interrupt controller. If we do not specify which IRQ controller to use the default is to use the next encountered IRQ controller as we climb the tree. This would be the DB8500. This patch ensures the AB8500 makes use of the correct interrupt controller. Signed-off-by: Lee Jones <lee.jones@linaro.org> --- arch/arm/boot/dts/dbx5x0.dtsi | 1 + 1 file changed, 1 insertion(+)
