regulator_set_mode(9)

💅 regulator_set_mode(9) — set regulator operating mode 💅

okay so bestie, welcome to regulator_set_mode(9) from the Kernel API Manual ✨ this is the little kernel API page for setting a regulator’s operating mode, and we are keeping every detail cute and intact 💖

🌸 NAME 🌸

regulator_set_mode — set regulator operating mode

✨ SYNOPSIS ✨

int regulator_set_mode (struct regulator *regulator , unsigned int mode );

🎀 ARGUMENTS 🎀

• regulator — regulator source.
• mode — operating mode - one of the REGULATOR_MODE constants.

🦋 DESCRIPTION 🦋

okay so this one sets the regulator operating mode to increase regulator efficiency or improve regulation performance. that’s the whole serve 💅

⚠️ NOTE ⚠️

bestie, important: Regulator system constraints must be set for this regulator before calling this function, otherwise this call will fail. no cap, do the constraints first 😭

🔥 RETURN 🔥

0 on success or a negative error number on failure. periodt.
