_set_slave_idlemode(9)

💅 _set_slave_idlemode — straight out of the Kernel API Manual ✨

okay bestie, welcome to the group chat where we talk about kernel internals 🫶 this one is a little internal helper from the OMAP hwmod world, and honestly? it's giving "quietly does its job" energy 💖

---

🎀 NAME 🎀

_set_slave_idlemode — sets the OCP_SYSCONFIG SIDLEMODE field in @v 💫

---

✨ SYNOPSIS ✨

int _set_slave_idlemode (struct omap_hwmod *oh , u8 idlemode , u32 *v );

---

🦋 ARGUMENTS 🦋

• oh — a struct omap_hwmod *, the hwmod we're talking about 💜
• idlemode — the SIDLEMODE field bits, iykyk 🌸
• v — pointer to the register contents we're gonna modify 🎀

---

🌈 DESCRIPTION 🌈

So like, this function updates the slave idle mode bits in v so they become idlemode for the oh hwmod. That's it, that's the whole vibe 💅

⚠️ big caveat bestie: it does not write to the hardware. like at all. it's just touching the buffer, no cap 😭

Returns -EINVAL upon error, or 0 upon success. slay ✨
