STRUCT LINEAR_RANGE(9)

💖 struct linear_range(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a lil struct called struct linear_range and honestly? she's giving lookup-table royalty 👑✨

---

🌸 NAME 🌸

struct linear_range — a whole table of selector ⟷ value pairs, no cap 🎀

---

✨ SYNOPSIS ✨

struct linear_range {
    unsigned int min;
    unsigned int min_sel;
    unsigned int max_sel;
    unsigned int step;
 };

• min — the lowest value in the range, fr the bottom of the vibe check 💅
• min_sel — the lowest selector for the range 🍓
• max_sel — the highest selector for the range 🔥
• step — the value step size, like how much we're incrementing each time ⭐

---

🦋 Description 🦋

So what she does: this defines a lookup-table for a range of values 💖 The whole point is to help you out when you're looking for a register value that matches a certain physical measure (like voltage, bestie — think voltage ⚡).

She's usable when an increment of one in the register always results in a constant increment of the physical measure (like voltage, again 😌). Like, one step up in the register = one steady step up in the real-world number. Consistent. Iconic. Periodt 💅
