regulator_ma...linear_range(9)

🌸 regulator_map_voltage_linear_range — the kernel API manual page, bestie edition 🌸

okay so this is regulator_ma...linear_range(9) from the Kernel API Manual — literally the glow-up guide for regulator_map_voltage_linear_range. stay with me, it's cute and it's important 💅

---

✨ NAME ✨

regulator_map_voltage_linear_range — it's map_voltage() but make it multiple linear ranges. iconic behaviour only 🎀

---

🦋 SYNOPSIS 🦋

int regulator_map_voltage_linear_range (struct regulator_dev *rdev , int min_uV , int max_uV );

that's the whole signature, no notes, chef's kiss ✨

---

💖 ARGUMENTS 💖

• rdev — the regulator we're operating on. the main character of this whole situation 👑
• min_uV — the lower bound for voltage. the floor, the bare minimum, the "i will not be accepting less" 🌸
• max_uV — the upper bound for voltage. the ceiling, the limit, the "don't push it" 🫶

---

⭐ DESCRIPTION ⭐

so if you're a driver and you've got linear_ranges chillin' in your descriptor? you can literally use this as your map_voltage callback. that's it, that's the whole vibe. no cap 🔥

it's giving "drop-in replacement, zero drama" and honestly? we love that for you 💜

ngl this page is short but it's mighty — if you're writing a regulator driver with linear_ranges in the descriptor, this callback is the one. slay 🦋

kisses and a little sign-off: this one's straight out of the kernel source tree at ./drivers/regulator, dated October 2026, and yeah — the page is regulator_ma...linear_range(9), same as it ever was. ily, go map some voltages 💅🎀⭐
