pf9453_regu...sable_regmap(9)

💅 pf9453_regulator_disable_regmap — from the Kernel API Manual, bestie

okay so picture this: it's a kernel API manual page, the vibe is immaculate, and the function we're stanning today is pf9453_regulator_disable_regmap. she's a manual page 9 entry, she lives in the kernel, and she is literally just here to turn a regulator off for the regmap girlies. no cap. 🎀

✨ NAME ✨

pf9453_regulator_disable_regmap — disable regulator for regmap users 🫶

like, that's the whole job. she disables. for the regmap users specifically. iconic behavior honestly.

---

🌸 SYNOPSIS 🌸

int pf9453_regulator_disable_regmap (struct regulator_dev *rdev );

that's it, that's the whole signature. one (1) argument, returns an int. the way she keeps it simple?? obsessed. ✨

---

🦋 ARGUMENTS 🦋

• rdev — regulator to operate on 💜

that's the regulator you're operating on, bestie. she's the main character here, you just hand her over and let the function do her thing.

---

💖 DESCRIPTION 💖

okay so here's the tea 🍵 — regulators that use regmap for their register I/O can set the enable_reg and enable_mask fields in their descriptor, and then use this function as their disable operation.

and that's the flex: it saves some code. that's it. that's the whole point. you don't gotta hand-roll your own disable op, you just point at this one and the enable_reg / enable_mask situation handles itself. lowkey elegant, highkey slay. 💅

so: enable_reg ✅, enable_mask ✅ — set them in the descriptor, use this as the disable op, save yourself some code. periodt. 🔥

---

👑 RETURN 👑

0 on success, or negative errno. 😭

so like — zero means we ate, negative errno means something went sideways. check it, don't ignore it, iykyk. 🩷

fr fr check that return value. a negative errno is your code telling you something happened and you're just gonna ignore her?? 🙈

go read the source file too, she's got the full lore. the enable one is basically her sister, and the voltage-select and ramp-delay ones are the rest of the squad. all linked, all worth a peek. 🧚
