drm_of_lvds_...data_mapping(9)

💅 drm_of_lvds_get_data_mapping(9) — the Kernel API Manual, but make it iconic 🎀

okay so bestie, welcome to the drm_of_lvds_get_data_mapping page of the Kernel API Manual — yes that whole name is a mouthful, but she's worth it, trust 💖

---

✨ NAME ✨

drm_of_lvds_get_data_mapping — literally just "Get LVDS data mapping", no cap, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

int drm_of_lvds_get_data_mapping (const struct device_node *port );

like... she takes one thing and she gives you back an int, that's the entire relationship 😭

---

🎀 ARGUMENTS 🎀

• port — the DT port node of the LVDS source or sink. That's it. That's the whole argument. she's low maintenance, we love her for it 🙈

---

💫 DESCRIPTION 💫

so what does she actually do? she takes the DT "data-mapping" property string value and converts it into a media bus format value. that's the glow-up: string in, format value out. main character energy fr fr 👑

---

🔥 RETURN 🔥

here's the part where she gives you something back — and bestie, the options are giving variety:

• MEDIA_BUS_FMT_RGB666_1X7X3_SPWG — when the data-mapping is "jeida-18" 💜
• MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA — when the data-mapping is "jeida-24" 💜
• MEDIA_BUS_FMT_RGB101010_1X7X5_JEIDA — when the data-mapping is "jeida-30" 💜
• MEDIA_BUS_FMT_RGB888_1X7X4_SPWG — when the data-mapping is "vesa-24" 🌈
• MEDIA_BUS_FMT_RGB101010_1X7X5_SPWG — when the data-mapping is "vesa-30" 🌈
• -EINVAL — when the "data-mapping" property is unsupported 💀 like, she doesn't know her, she's not gonna pretend
• -ENODEV — when the "data-mapping" property is missing 😭 gone, not found, she looked everywhere

ngl the -EINVAL vs -ENODEV difference matters, bestie — one means "that value isn't a thing I support," the other means "there's no value at all." different problems, different drama 💅
