regulator_enable(9)

🌸 NAME 🌸

okay bestie, welcome to regulator_enable(9) from the Kernel API Manual 💖 this page is all about regulator_enable — enable regulator output ✨

✨ SYNOPSIS ✨

the signature is literally giving:

int regulator_enable (struct regulator *regulator );

🎀 ARGUMENTS 🎀

• regulator — regulator source 🫶

💅 DESCRIPTION 💅

okay so here’s the whole vibe: request that the regulator be enabled with the regulator output at the predefined voltage or current value. that’s the main character move, no cap ✨

and the rule you cannot skip: calls to regulator_enable must be balanced with calls to regulator_disable. like, every enable needs its matching disable, periodt 💖

🙈 NOTE 🙈

heads up bestie: the output value can be set by other drivers, boot loader or may be hardwired in the regulator. iykyk 💀

🍓 RETURN 🍓

0 on success or a negative error number on failure. that’s it, that’s the tea 🍓
