ti_abb_set_opp(9)

💅 ti_abb_set_opp(9) — kernel API manual, bestie edition 🎀

okay so bestie, welcome to the glow-up docs for ti_abb_set_opp — the little kernel function that sets up ABB and LDO VBB for the bias you actually need. it's giving "background support character who's secretly carrying the whole plot" ✨

---

✨ NAME ✨

ti_abb_set_opp — setup ABB and LDO VBB for the required bias, no cap 💅

---

🌸 SYNOPSIS 🌸

int ti_abb_set_opp (struct regulator_dev *rdev , struct ti_abb *abb ,
struct ti_abb_info *info );

like… that's the whole signature, and yes it's int because it's gonna tell you how it went 🫶

---

🦋 ARGUMENTS 🦋

• rdev — the regulator device, literally the main character of this whole hardware situation 👑
• abb — pointer to the abb instance, iykyk, it's the ABB we're working with
• info — the ABB info that's gonna get programmed 💖

---

⭐ RETURN ⭐

0 on success, or whatever the appropriate error value is when it fails 😭 (it happens, we don't gatekeep failure)

---

🌈 SEE ALSO 🌈

heads up bestie, the kernel file lives at ./drivers/regulator/ti-abb-regulator.c — that's the mothership 🧚

ngl this one's short and sweet — read the whole gang above before you start poking at bias registers, fr fr 🙈
