| D | TODO | 4 * Convert the GPIO driver to use the GPIO irqchip library
|
| /Linux-v4.19/Documentation/driver-api/gpio/ |
| D | driver.rst | 217 The IRQ portions of the GPIO block are implemented using an irqchip, using
227 on an irqchip. Create the callbacks if needed [2].
234 system interrupt controller. This means that the GPIO irqchip handler will
235 be called immediately from the parent irqchip, while holding the IRQs
236 disabled. The GPIO irqchip will then end up calling something like this
251 If required (and if it can't be converted to the nested threaded GPIO irqchip)
269 The GPIO irqchip will then end up calling something like this sequence in
281 other GPIO irqchip residing on the other side of a sleeping bus. Of course
302 * gpiochip_irqchip_add(): adds a chained irqchip to a gpiochip. It will pass
308 * gpiochip_irqchip_add_nested(): adds a nested irqchip to a gpiochip.
