ENUM K230_RST_TYPE(9)

✨ enum k230_rst_type(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 we're talking about enum k230_rst_type and honestly? it's giving "small but iconic." let's get into it 🎀

---

🌸 NAME 🌸

enum k230_rst_type — the K230 reset types, aka the whole vibe check for how resets behave on this chip 👑

---

🦋 SYNOPSIS 🦋

enum k230_rst_type {
    RST_TYPE_CPU0 ,
    RST_TYPE_CPU1 ,
    RST_TYPE_FLUSH ,
    RST_TYPE_HW_DONE ,
    RST_TYPE_SW_DONE

};

literally the entire enum, no notes 💖

---

⭐ Constants ⭐

okay this is the part where you actually need to pay attention, bestie, because each one of these has its own whole personality 🫶

• RST_TYPE_CPU0 — the reset type for CPU0. it automatically clears, and it's got a write enable and a done bit, and it's active high. so iconic of it ✨
• RST_TYPE_CPU1 — reset type for CPU1. this one manually clears (not like its sibling, periodt), and it has a write enable and a done bit, active high 💫
• RST_TYPE_FLUSH — reset type for the CPU L2 cache flush. automatically clears, has a write enable, but no done bit — and it's active high. lowkey the minimal one of the group 🧚
• RST_TYPE_HW_DONE — reset type for hardware auto clear. automatically clears, no write enable, but it does have a done bit, active high. it's giving "done bit main character energy" 👑
• RST_TYPE_SW_DONE — reset type for software manual clear. manually clears, and here's the moment — it has no write enable and no done bit. and the polarity? active high if the ID is RST_SPI2AXI, otherwise active low. yes bestie, conditional polarity, we love a plot twist 😭

fr fr do not sleep on that last one — the RST_SPI2AXI condition is the whole thing. miss it and you're gonna have a bad time 💀
