🌸 NAME 🌸

dev_pm_set_wake_irq — Attach device IO interrupt as wake IRQ 🦋

---

✨ SYNOPSIS ✨

int dev_pm_set_wake_irq (struct device *dev , int irq );

---

💖 ARGUMENTS 💖

• dev — Device entry. Like, the device in question, bestie. 🫶
• irq — Device IO interrupt. The interrupt that’s about to get its wake-IRQ moment. ⭐

---

🦋 DESCRIPTION 🦋

Attach a device IO interrupt as a wake IRQ. Periodt. 💅

The wake IRQ gets automatically configured for wake-up from suspend based on the device specific sysfs wakeup entry. So it’s not doing mystery magic — it’s tied to that sysfs wakeup situation. 🔥

Typically called during driver probe after calling device_init_wakeup. That’s the vibe check: driver probe first, device_init_wakeup first, then this. Ngl, order matters, iykyk. 🌈
