mipi_dsi_dcs_soft_reset(9)

💅 mipi_dcs_soft_reset — wait, no, mipi_dsi_dcs_soft_reset 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's short but she's got lore, so buckle up 🎀

---

🌸 NAME 🌸

mipi_dsi_dcs_soft_reset — perform a software reset of the display module 🫶

---

⭐ SYNOPSIS ⭐

int mipi_dsi_dcs_soft_reset (struct mipi_dsi_device *dsi );

no cap, that's the whole signature. one arg. she's lowkey minimal 💅

---

🦋 ARGUMENTS 🦋

• dsi — the DSI peripheral device ✨ that's it, that's the parameter. it's the display module bestie you're resetting 🎀

---

🔥 DESCRIPTION 🔥

so here's the tea, and it's important tea, so listen up 🙈

this function is deprecated. like, the kernel is literally telling you to move on 😭 use mipi_dsi_dcs_soft_reset_multi instead. periodt. 💀

that's genuinely the whole description — short, iconic, a little tragic 🎀 the function still does a software reset of the display module, but the docs are out here saying "bestie, use the other one" and honestly? respect the honesty 💅

---

🌈 RETURN 🌈

• 0 on success 🎉 (slay)
• a negative error code on failure 😭 (not slay)

that's the whole vibe check: zero = good, negative = bad 🫶
