regulator_hardware_enable(9)

🎀 regulator_hardware_enable(9) — straight from the Kernel API Manual 🎀

Ok bestie, buckle up: today’s main character is regulator_hardware_enable, and it’s giving “let me touch the hardware so this regulator can do its thing.” ✨

📛 NAME 📛

regulator_hardware_enable — access the HW for enable/disable regulator. That’s the whole errand, and honestly? Iconic. 💅

🧾 SYNOPSIS 🧾

int regulator_hardware_enable (struct regulator *regulator , bool enable
);

🫶 ARGUMENTS 🫶

• regulator — regulator source. This is the regulator we’re talking about, bestie.
• enable — true for enable, false for disable. Literal booleans, no vibes-based guessing.

💡 DESCRIPTION 💡

Request that the regulator be enabled/disabled with the regulator output at the predefined voltage or current value. So yes: we’re asking for the enable/disable hardware moment, with the output sitting at that predefined voltage or current value. No cap, that’s the vibe. 🦋

🔁 RETURN 🔁

0 on success or a negative error number on failure. Zero is slay; a negative error number is the “bestie, something went wrong 😭” path.
