ENUM SDW_STREAM_TYPE(9)

✨ enum sdw_stream_type(9) ✨

straight outta the Kernel API Manual, bestie 💖

okay so picture this: you're deep in the SoundWire headers and suddenly there's a enum sdw_stream_type staring at you like 👁️👄👁️ and you're like "what even IS this". Don't panic. It's literally just a little enum that says what kind of data stream you're dealing with. That's it. That's the whole vibe. 🎀

---

🌸 NAME 🌸

enum sdw_stream_type — data stream type, no cap 💅

---

🦋 SYNOPSIS 🦋

enum sdw_stream_type {
    SDW_STREAM_PCM ,
    SDW_STREAM_PDM ,
    SDW_STREAM_BPT

};

look at her. so small. so iconic. 🫶 (yes there's a lil blank line before the closing brace, that's canon, don't @ me)

---

🍓 Constants 🍓

these are the three besties in the enum, and here's what each one means:

• SDW_STREAM_PCM — a PCM data stream ✨
• SDW_STREAM_PDM — a PDM data stream 🌸
• SDW_STREAM_BPT — a BPT data stream 💜

three constants, three vibes, all valid. periodt.

---

🌈 Description 🌈

okay so here's the tea ☕: the spec doesn't define this, but is used in implementation.

that's the whole description. the spec left us on read, but the implementation said "i'll handle it" and honestly? main character energy. 🔥

real talk though — this is a documented-in-code-only situation, so if you're looking for the official spec section, it's giving "does not exist". the implementation is the source of truth here, iykyk.
