| D | TODO | 88 GPIOLIB irqchip
90 The GPIOLIB irqchip is a helper irqchip for "simple cases" that should
91 try to cover any generic kind of irqchip cascaded from a GPIO.
93 - Convert all the GPIOLIB_IRQCHIP users to pass an irqchip template,
95 Currently we set up the irqchip after setting up the gpiochip
98 the irqchip before registering the gpio_chip, typical example:
100 /* Typical state container with dynamic irqchip */
110 /* Set up the irqchip dynamically */
134 dry-code conversions to gpiolib irqchip for maintainers to test
