sta350_set_bias_level(9)

🎀 NAME 🎀

sta350_set_bias_level is living in the Kernel API Manual, section 9, and it is literally a DAPM callback. Bestie, that's the whole vibe. 💅✨

✨ SYNOPSIS ✨

int sta350_set_bias_level (struct snd_soc_component *component , enum snd_soc_bias_level level );

💖 ARGUMENTS 💖

• component — the component device 🫶
• level — DAPM power level ⚡

🦋 DESCRIPTION 🦋

OK so ALSA calls this to put the component into low power mode or to wake it up. That's the whole job, and it's iconic. 🌸

And listen: if the component is powered off completely, all registers must be restored after power on. Not some of them. All of them. No cap. 😭💀
