zynqmp_dp_link_train_cr(9)

💅 zynqmp_dp_link_train_cr 💅

okay bestie, welcome to the Kernel API Manual entry for zynqmp_dp_link_train_cr(9) — yes that's the section number, yes we're fancy now, section 9 is the kernel-API section, iykyk ✨

---

🌸 NAME 🌸

zynqmp_dp_link_train_cr — Train clock recovery 🎀

like literally, that's the whole job. it trains. the clock. recovery. slay.

---

✨ SYNOPSIS ✨

int zynqmp_dp_link_train_cr (struct zynqmp_dp *dp );

one function, one argument, one int coming back at you. no cap, that's the entire synopsis 💖

---

🦋 ARGUMENTS 🦋

• dp — the DisplayPort IP core structure. that's it. handed to you, you pass it in, she's the main character of this whole call 🫶

---

👑 RETURN 👑

so what does she give back?

• 0 — clock recovery train is done successfully 🎉 periodt, we love a zero.
• or corresponding error code — anything not-zero means something went sideways, and it'll be the matching error code 😭

fr fr, 0 = clock recovery trained successfully. not-0 = the corresponding error code. that's the vibe check 💀
