Hi, this is a respin of getting the support for the Layerscape's external interrupt lines. The last version from Rasmus Villemoes can be found here: https://lkml.kernel.org/r/20180223210901.23480-1-rasmus.villemoes@xxxxxxxxx/ Rasmus Villemoes ran out of time, so I prepared v6. Changes since v5: - Rebase to v5.3.0 - Integrated Thomas Gleixner comments: - Adjust order of local variables - Use irq_chip_set_type_parent() - Cleanup of irq headers - Integrated Rob Herring comments: - Add #address-cells and #size-cells to parent - Use ARCH_LAYERSCAPE, as this feature is not LS1021A specific It is tested on a Layerscape LS2088A.
