[PATCH/RFC] drivers/irqchip: add irq-inverter

Each devres entry is associated with a release function. A devres can be released in several ways. No matter what, all devres entries are released on driver detach. On release, the associated release function is invoked and then the devres entry ... A more natural abstraction is the clean separation of the ‘irq flow’ and the ‘chip details’. Analysing a couple of architecture’s IRQ subsystem implementations reveals that most of them can use a generic set of ‘irq flow’ methods and only need to add the chip-level specific code. flower yokai
