irqdomain: Allow software nodes for IRQ domain creation
In some cases we need to have an IRQ domain created out of software node. One of such cases is DesignWare GPIO driver when it's instantiated from half-baked ACPI table (alas, we can't fix it for devices which are few years on market) and thus using software nodes to quirk this. But the driver is using IRQ domains based on per GPIO port firmware nodes, which are in the above case software ones. This brings a warning message to be printed [ 73.957183] irq: Invalid fwnode type for irqdomain and creates an anonymous IRQ domain without a debugfs entry. Allowing software nodes to be valid for IRQ domains rids us of the warning and debugs gets correctly populated. % ls -1 /sys/kernel/debug/irq/domains/ ... intel-quark-dw-apb-gpio:portA Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> [maz: refactored commit message] Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20200520164927.39090-3-andriy.shevchenko@linux.intel.com
