mipi_dsi_dc...lumn_address(9)

💅 mipi_dsi_dcs_set_column_address — NAME

ok so this is a Kernel API Manual page, and the star of the show is mipi_dsi_dcs_set_column_address ✨ — it defines the column extent of the frame memory accessed by the host processor. that's literally the whole vibe: you're telling the display "hey bestie, your frame memory columns live here". 💖

also real quick jsyk — the header on this one is truncated to mipi_dsi_dc...lumn_address(9) because it's too iconic for one line 🎀

---

🦋 SYNOPSIS

int mipi_dsi_dcs_set_column_address (struct mipi_dsi_device *dsi , u16
start , u16 end );

like, that's the whole signature, no cap. it returns an int, takes a struct mipi_dsi_device *, and two u16s. 🫶

🌸 ARGUMENTS

• dsi — the DSI peripheral device. this is your main character, the display you're talking to 💅
• start — first column of frame memory. the beginning of the story 🎬
• end — last column of frame memory. where it all wraps up 🎀

---

💀 DESCRIPTION

okay bestie i have to be the one to tell you: this function is deprecated. 😭

use mipi_dsi_dcs_set_column_address_multi instead. that's the upgraded model, the glow-up, the one you actually want. don't be out here calling the old one unless you have to. 🙈

fr fr, deprecated means deprecated — reach for mipi_dsi_dcs_set_column_address_multi when you can.

---

⭐ RETURN

0 on success 💖 or a negative error code on failure 😭. that's it, that's the whole check. no in-between, no drama.
