💅 zynqmp_r5_setup_mbox(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's about zynqmp_r5_setup_mbox, and it's genuinely a lil function with a big job 🎀

---

✨ NAME ✨

zynqmp_r5_setup_mbox — sets up the mailboxes-related properties, and like… it does this for each individual R5 core 🦋 like one at a time, every single core gets its own little setup moment. main character treatment fr.

---

🌸 SYNOPSIS 🌸

struct mbox_info * zynqmp_r5_setup_mbox (struct device *cdev );

---

🫶 ARGUMENTS 🫶

• cdev — the child node device 💖 that's the one thing you hand it. that's it. that's the whole vibe check.

---

💫 DESCRIPTION 💫

so basically this is the function that sets up the mailboxes-related properties 📬✨ that's the entire job description, no cap. it handles the setup, it does the thing, and then it's done. iconic behaviour honestly.

---

🔥 RETURN 🔥

• NULL if it failed 😭 — like, nothing came back, the setup flopped
• otherwise, a pointer to mbox_info 👑 — success, slay, you got your struct

no middle ground bestie — it's either NULL or a whole pointer to mbox_info, so please check before you go dereferencing anything 💀
