regmap_irq_...q_reg_linear(9)

💅 NAME 💅

regmap_irq_get_irq_reg_linear — the linear IRQ register mapping callback, bestie. That's it, that's the whole gig. ✨

---

🎀 SYNOPSIS 🎀

unsigned int regmap_irq_get_irq_reg_linear (struct regmap_irq_chip_data
       *data , unsigned int base , int index );

---

🌸 ARGUMENTS 🌸

• data — the data for the struct regmap_irq_chip. Like, the whole vibe of your chip lives in here. 🫶
• base — the base register. The starting point, the home base, the main character. 👑
• index — the register index. Which one you're reaching for, one by one down the line. 💫

---

✨ DESCRIPTION ✨

Okay so here's the tea, bestie — this function hands you back the register address that lines up with the base and index you passed in. No cap, it literally just does the formula:

base + index * regmap_stride * irq_reg_stride

That's it. That's the whole function. Linear mapping, one formula, no drama. It's giving "simple and iconic" and honestly? Obsessed. 🦋

That's a wrap, babe — brought to you by the fine people over at ./drivers/base/regmap, stamped October 2026, and yes the man page header still says regmap_irq_...q_reg_linear(9) because truncation said "not me being mysterious" 💀 slay, go map some registers. 🍓
