gpiochip_irq...n_deactivate(9)

💖 gpiochip_irq...n_deactivate(9) 💖

okay so we're in the Kernel API Manual, and this page is literally all about gpiochip_irq_domain_deactivate — the "unlock a GPIO used as an IRQ" girlie. honestly? iconic, short, specific, and serving exactly what it needs to serve. no cap. 💅

✨ NAME ✨

gpiochip_irq_domain_deactivate — Unlock a GPIO used as an IRQ

🦋 SYNOPSIS 🦋

void gpiochip_irq_domain_deactivate (struct irq_domain *domain , struct
       irq_data *data );

💅 ARGUMENTS 💅

• domain — The IRQ domain used by this IRQ chip
• data — Outermost irq_data associated with the IRQ

🌸 DESCRIPTION 🌸

okay so here's the tea: this function is a wrapper that will call gpiochip_unlock_as_irq, and it is to be used as the deactivate function for the struct irq_domain_ops. periodt. the host_data for the IRQ domain must be the struct gpio_chip — like, that's the vibe check it has to pass. no cap.
