STRUCT MT7621_PCIE_PORT(9)

✨ struct mt7621_pcie_port(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 today's main character is struct mt7621_pcie_port — it's literally the PCIe port information struct and it's giving "I hold everything together" energy 👑

---

🌸 NAME 🌸

struct mt7621_pcie_port — PCIe port information 🎀

like, all the deets about one port, in one struct. no cap.

---

🦋 SYNOPSIS 🦋

struct mt7621_pcie_port {
    void __iomem *base;
    struct list_head list;
    struct mt7621_pcie *pcie;
    struct clk *clk;
    struct phy *phy;
    struct reset_control *pcie_rst;
    struct gpio_desc *gpio_rst;
    u32 slot;
    bool enabled;
 };

(yeah there's a lil extra space before that closing brace in the original — we respect the canon 💅)

🧚 MEMBERS 🧚

• base — the I/O mapped register base ⭐ that's where the registers live, mapped in.
• list — port list 📋 it's a struct list_head, so this port is one node in a linked list. iconic behavior.
• pcie — pointer to PCIe host info 🔥 points back at the struct mt7621_pcie that owns it.
• clk — pointer to the port clock gate 🕰️ the clock, gated, as one does.
• phy — pointer to PHY control block 🌈 the PHY stuff lives over here.
• pcie_rst — pointer to port reset control 🎀 reset control for the port, pointer style.
• gpio_rst — gpio reset 🙈 a reset that comes from a GPIO, iykyk.
• slot — port slot 🔢 it's a u32 and it's the port's slot number.
• enabled — indicates if port is enabled 💀 a bool, true/false, is the port on or not. vibe check for the port, basically.

fr fr: every field above is exactly as written, and enabled is literally just "indicates if port is enabled" — that's the whole spec, don't come for me 😭
