Gpiochip_set_chained_irqchip
Web* gpiochip_set_chained_irqchip(): sets up a chained irq handler for a gpio_chip from a parent IRQ and passes the struct gpio_chip* as handler data. (Notice handler data, since the irqchip data is likely used by the parent irqchip!) This is for the chained type of chip. This is also used to set up a nested irqchip if NULL is passed as handler.

WebThis provides a function gpiochip_irqchip_add() to set up an irqchip for a GPIO controller, and a function gpiochip_set_chained_irqchip() to chain it to a parent irqchip. Most GPIOs are of the type where a number of lines form a cascaded interrupt controller chained onto the primary system interrupt controller (or further down the rbc sherbrooke est montrealWebOn Tue, Apr 15, 2014 at 8:43 AM, Barry Song <[email protected]> wrote: > From: Linus Walleij > > This switches the SiRF pinctrl driver over to using the gpiolib > irqchip helpers simplifying some of the code. > > Signed-off-by: Barry Song Patch applied!
