✨ zynqmp_dp_set_format(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's about zynqmp_dp_set_format — the little function that says "hey DisplayPort, here's the input format, deal with it" 💅

---

🌸 NAME 🌸

zynqmp_dp_set_format — Set the input format 🎀

---

🦋 SYNOPSIS 🦋

int zynqmp_dp_set_format (struct zynqmp_dp *dp , const struct
drm_display_info *info , enum zynqmp_dpsub_format format , unsigned int
bpc );

---

💖 ARGUMENTS 💖

• dp — the DisplayPort IP core structure 🫶 like, the main character of this whole thing
• info — Display info ✨
• format — the input format 🌈
• bpc — bits per component, no cap 🧚

---

⭐ DESCRIPTION ⭐

So basically 👑 it updates the misc register values based on the input format and bpc. That's it, that's the vibe check. Lowkey iconic how simple it is.

---

🔥 RETURN 🔥

0 on success, or -EINVAL 😭 (yes, she will absolutely hit you with a -EINVAL if things aren't giving)
