mipi_dsi_dc...y_brightness(9)

✨ mipi_dsi_dc...y_brightness(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this is the page for mipi_dsi_dc...y_brightness(9) — yes that's the real title, the truncation is giving legacy and we respect it 🎀

---

🌸 NAME 🌸

mipi_dsi_dcs_set_display_brightness — sets the brightness value of the display 💡✨

---

🦋 SYNOPSIS 🦋

int mipi_dsi_dcs_set_display_brightness (struct mipi_dsi_device *dsi ,
u16 brightness );

---

🎀 ARGUMENTS 🎀

• dsi — the DSI peripheral device, aka the screen in question 🖥️
• brightness — the brightness value you want to throw at it, a u16 🔆

---

💅 DESCRIPTION 💅

Okay so, heads up bestie — this function is deprecated 😭 like, it still exists, but the kernel devs are gently pushing you toward the new one. Use mipi_dsi_dcs_set_display_brightness_multi instead. That's the move. That's the upgrade. Periodt 👑

---

🌈 RETURN 🌈

0 on success, or a negative error code on failure 💀 — no in-between, no cap.

✨ iykyk: a negative return means something went sideways, so go check it 🫶

that's the whole thing bestie, you ate that read 💜✨ this page lives over in ./drivers/gpu/drm and it's dated October 2026 — go forth and set some display brightness (with the _multi version, obviously 🙈💅) 🦋🌸
