the irqchip can initialize. E.g. .dev and .can_sleep shall be set up
properly.
-- Nominally set all handlers to handle_bad_irq() in the setup call and pass
- handle_bad_irq() as flow handler parameter in gpiochip_irqchip_add() if it is
- expected for GPIO driver that irqchip .set_type() callback will be called
- before using/enabling each GPIO IRQ. Then set the handler to
- handle_level_irq() and/or handle_edge_irq() in the irqchip .set_type()
- callback depending on what your controller supports and what is requested
- by the consumer.
+- Nominally set gpio_irq_chip.handler to handle_bad_irq. Then, if your irqchip
+ is cascaded, set the handler to handle_level_irq() and/or handle_edge_irq()
+ in the irqchip .set_type() callback depending on what your controller
+ supports and what is requested by the consumer.
