[ Upstream commit dde286ee57 ]
When multiple IRQ domains are created from the same device-tree node they
will get the same name based on the device-tree path. This will cause a
naming collision in debugFS when IRQ domain specific entries are created.
The regmap-IRQ creates per instance IRQ domains. This will lead to a
domain name conflict when a device which provides more than one
interrupt line uses the regmap-IRQ.
Add support for specifying an IRQ domain name suffix when creating a
regmap-IRQ controller.
