ENUM V4L2_MBUS_TYPE(9)

✨ enum v4l2_mbus_type ✨

okay bestie, so this one's from the Kernel API Manual (that's the manual name, iykyk 💅) and it's literally just a little enum that tells you what kind of media bus you're dealing with. tiny page, huge vibe. let's get into it 🎀

💖 Constants 💖

okay so here's the whole crew, one by one, no skips, no cap:

• V4L2_MBUS_UNKNOWN — unknown bus type, and no V4L2 mediabus configuration either. it's the "we don't know her" of bus types 🙈
• V4L2_MBUS_PARALLEL — parallel interface with hsync and vsync. classic. reliable. lowkey iconic.
• V4L2_MBUS_BT656 — parallel interface with embedded synchronisation, and it can also be used for BT.1120. versatile queen ✨
• V4L2_MBUS_CSI1 — MIPI CSI-1 serial interface. the og serial one 🦋
• V4L2_MBUS_CCP2 — CCP2 (Compact Camera Port 2). compact and cute, just like the name says 🎀
• V4L2_MBUS_CSI2_DPHY — MIPI CSI-2 serial interface, with D-PHY. yes bestie, the D matters 💅
• V4L2_MBUS_CSI2_CPHY — MIPI CSI-2 serial interface, with C-PHY. and yes, the C matters too 😌
• V4L2_MBUS_DPI — MIPI VIDEO DPI interface. video girlie 🎥
• V4L2_MBUS_INVALID — invalid bus type, and the page literally says (keep as last). do NOT move her. she's the final boss, she stays at the end 👑
