💅 tps65090_fet_enable(9) — Kernel API Manual energy ✨

🎀 NAME 🎀

tps65090_fet_enable — Enable a FET, trying a few times if it fails 💖

✨ SYNOPSIS ✨

int tps65090_fet_enable (struct regulator_dev *rdev );

🫶 ARGUMENTS 🫶

• rdev — Regulator device. That's the whole vibe for this one 🎀

🌸 DESCRIPTION 🌸

okay so some versions of the tps65090 have issues when turning on the FETs 😭 no cap.

This function goes through several steps to ensure the best chance of the FET going on. Specifically:

• We'll make sure that we bump the "overcurrent wait" to the maximum, which increases the chances that we'll turn on properly 🔥
• We'll retry turning the FET on multiple times (turning off in between) 🔁

⭐ RETURN ⭐

0 if ok, non-zero if it fails. That's it, that's the return vibe 💅
