232 interrupt controller and those irq_domains are organized into hierarchy.
233 When building irq_domain hierarchy, the irq_domain near to the device is
234 child and the irq_domain near to CPU is parent. So a hierarchy structure
245 There are four major interfaces to use hierarchy irq_domain:
256 Following changes are needed to support hierarchy irq_domain:
259 maintain irq_domain hierarchy information.
261 build hierarchy irq_data to match hierarchy irq_domains. The irq_data
263 3) new callbacks are added to struct irq_domain_ops to support hierarchy
266 With support of hierarchy irq_domain and hierarchy irq_data ready, an
269 IRQ. Now we could go one step further to support stacked(hierarchy)
271 the hierarchy. A child irq_chip may implement a required action by
279 For an interrupt controller driver to support hierarchy irq_domain, it
288 they are unused with hierarchy irq_domain.
