regmap_irq_get_domain(9)

💖 regmap_irq_get_domain(9) 💖

okay so welcome to the Kernel API Manual, bestie — today’s main character is regmap_irq_get_domain(9), and it’s giving “kernel driver but make it cute” energy 💅✨

✨ NAME ✨

regmap_irq_get_domain — Retrieve the irq_domain for the chip 🎀

🌸 SYNOPSIS 🌸

struct irq_domain * regmap_irq_get_domain (struct regmap_irq_chip_data
       *data );

🦋 ARGUMENTS 🦋

• data — the regmap_irq controller to operate on, bestie 🫶

🔥 DESCRIPTION 🔥

So this one is useful for drivers that wanna request their own IRQs, and for integration with subsystems — very “let me handle my own business” energy 😌

For ease of integration, NULL is accepted as a domain, which lets devices just call this even if no domain is allocated. No cap, that’s the whole point: easy integration, no extra drama ✨
