STRUCT REGMAP_IRQ_TYPE(9)

✨ struct regmap_irq_type(9) ✨

okay so bestie, this is struct regmap_irq_type(9) from the Kernel API Manual, and it is literally the glow-up guide for your IRQ types 💅 like it's the struct that tells the regmap IRQ machinery how to poke your device's registers so an interrupt knows whether it's rising, falling, level-low or level-high. no cap, it's giving "configuration blueprint" energy and we are obsessed 🎀

🌸 NAME 🌸

struct regmap_irq_type — IRQ type definitions. that's it, that's the vibe ✨

---

🦋 SYNOPSIS 🦋

struct regmap_irq_type {
    unsigned int type_reg_offset;
    unsigned int type_reg_mask;
    unsigned int type_rising_val;
    unsigned int type_falling_val;
    unsigned int type_level_low_val;
    unsigned int type_level_high_val;
    unsigned int types_supported;
 };

look at her. seven unsigned int fields, all main character energy 👑 and yes you have to keep them exactly like that, don't touch the formatting, she's perfect 💖

---

🎀 Members 🎀

so here's the member-by-member breakdown, bestie, and every single one matters:

• type_reg_offset — the offset register for the irq type setting. this is where the type config actually lives 📍
• type_reg_mask — the device interrupt mask. mask it, queen 🎭
• type_rising_val — the register value you write to configure a RISING type irq. going up? this is the value ⬆️✨
• type_falling_val — the register value to configure a FALLING type irq. going down? same deal, different value ⬇️💜
• type_level_low_val — the register value to configure a LEVEL_LOW type irq. lowkey level-triggered 🍓
• type_level_high_val — the register value to configure a LEVEL_HIGH type irq. highkey level-triggered 🔥
• types_supported — a logical OR of IRQ_TYPE_* flags indicating the supported types. this is the vibe check for what your chip can actually do ✅

fr fr, keep those flag names and values exactly as written — RISING, FALLING, LEVEL_LOW, LEVEL_HIGH, and IRQ_TYPE_* are literal, not a mood 🌈
