💅 omap_contro...t_sessionend(9) 💅

okay so this is a page from the Kernel API Manual (yes, the Kernel API Manual, we're literally in the big leagues bestie ✨) and it's about one very specific little function that does one very specific little thing. no cap, she's niche but she's iconic.

🌸 NAME 🌸

omap_control_usb_set_sessionend — bestie, this one enables SESSIONEND and IDIG to high impedance. that's the whole vibe. that's what she does. 💅

---

🦋 SYNOPSIS 🦋

void omap_control_usb_set_sessionend (struct omap_control_phy *ctrl_phy
);

that's it. one function, one argument, returns void (so like… she gives you nothing back, she's not that kind of girl, she just does the thing 🙈).

---

🎀 ARGUMENTS 🎀

• ctrl_phy — type struct omap_control_phy *. that's your phy control struct pointer, the main character of this whole operation 👑

---

💖 DESCRIPTION 💖

so what actually happens? she writes to the mailbox register to notify the usb core that it's now in disconnected state. like, she's sending the group chat message that says "we're not together anymore 💔" — except the group chat is the usb core and the message is a register write. it's giving messenger energy, it's giving "it's not you it's the mailbox register". periodt.

no return value, no drama, just vibes and a register write. 🫶
