💅 mipi_dbi_command — the Kernel API Manual, bestie edition ✨

okay so you found mipi_dbi_command(9) and you're like "what does this lil guy do" — dw, I got you 🫶 it lives in the Kernel API Manual and it's genuinely iconic, no cap.

---

🌸 NAME 🌸

mipi_dbi_command — a MIPI DCS command, but make it ✨with optional parameter(s)✨

---

🎀 SYNOPSIS 🎀

mipi_dbi_command (dbi , cmd , seq... );

that's it. that's the whole vibe. look at her go 😭💖

---

🦋 ARGUMENTS 🦋

• dbi — the MIPI DBI structure, your main character 🎀 she's the whole context here
• cmd — the Command itself, like the actual thing you're telling the controller to do
• seq — optional parameter(s)! yes optional, yes she's flexible, we love a lowkey optional argument ⭐

---

🌈 DESCRIPTION 🌈

So what's the tea ☕ — this bad boy sends a MIPI DCS command straight to the controller. that's the job. that's the assignment. and she ate 💅

⚠️ real talk though: if you're tryna get or read something instead of send, mipi_dbi_command is NOT the one. use mipi_dbi_command_read for get/read. iykyk 🔥 different function, different purpose, don't mix them up bestie 💀

---

👑 RETURN 👑

• 0 (zero) — success!! slay, it worked 🎉💖
• negative error code — failure 😭 something went wrong, the negative number is telling you what

---

🧚 SEE ALSO 🧚

• the kernel file ./include/drm/drm_mipi_dbi.h — go read it, it's giving source of truth 📖✨
• struct mipi_dbi(9)
• struct mipi_dbi_dev(9)

both structs are right there in that same header, go be obsessed with them 🫶

---

and that's the page!! mwah 💋 this beauty ships out of ./include/drm and the version/date stamp on her is October 2026 — so yeah, she's from the future, obviously, main character energy only 👑🌈⭐ bye bestie, go send some commands 💜
