STRUCT MTK_PCIE_PHY(9)

🌸 NAME 🌸

okay bestie, welcome to the Kernel API Manual — section 9 ofc — and today's main character is struct mtk_pcie_phy, which is literally the main structure of the PCIe phy driver. like, THE structure. periodt. 💅

✨ SYNOPSIS ✨

here's the whole glow-up, no notes:

struct mtk_pcie_phy {
    struct device *dev;
    struct phy *phy;
    void __iomem *sif_base;
    const struct mtk_pcie_phy_data *data;
    bool sw_efuse_en;
    u32 efuse_glb_intr;
    struct mtk_pcie_lane_efuse *efuse;
};

okay so let's meet the cast, one member at a time 🎀

• dev — pointer to device. iconic. the anchor of the whole friend group 💖
• phy — pointer to generic phy. the actual phy bestie, very demure, very mindful 🦋
• sif_base — IO mapped register base address of system interface. this is where the registers live, like the group chat of memory 🏠
• data — pointer to SoC dependent data. so every SoC gets to be its own unique little self, no cap 🍓
• sw_efuse_en — software eFuse enable status. it's a bool, it's giving yes/no, on/off, slay/fail ✨
• efuse_glb_intr — internal resistor selection of TX bias current data. lowkey a mouthful but it's literally just telling you what that u32 is for 💀
• efuse — pointer to eFuse data for each lane. every lane gets its own eFuse moment, we love lane equality 👑
