omap_rproc_request_timer(9)

✨ omap_rproc_request_timer(9) ✨

okay bestie, so this is a page straight out of the Kernel API Manual and it's literally all about grabbing a timer for a remoteproc 👑 no cap, it's more iconic than it sounds, i promise 🫶

---

🌸 NAME 🌸

omap_rproc_request_timer — request a timer for a remoteproc 💅

---

🦋 SYNOPSIS 🦋

int omap_rproc_request_timer (struct device *dev , struct device_node
*np , struct omap_rproc_timer *timer );

like, that's the whole vibe. three args, one int back. slay ✨

---

🎀 ARGUMENTS 🎀

• dev — the device that's requesting the timer, aka the one doing the asking 🙋‍♀️
• np — a device node pointer to the timer you actually want, like the address of your fave 🎯
• timer — a handle to a struct omap_rproc_timer, and this is where the timer handle gets returned to you 💖

---

💜 DESCRIPTION 💜

so this helper function is used primarily to request a timer that's associated with a remoteproc. that's the whole main character energy of it 🌟

the returned handle gets stored in the .odt field of the timer structure you passed in — yes, the exact field .odt, don't forget it 🎀 — and that handle is what you use to invoke the other timer-specific ops. like starting a timer either during device initialization or during a resume operation, or for stopping/freeing a timer. it's giving "one handle to rule them all" ngl 👑

---

🔥 RETURN 🔥

0 on success, otherwise an appropriate failure 😭 that's it, that's the return value. no cap.
