STRUCT MTK_PCIE_LANE_EFUSE(9)

okay so bestie, welcome to the struct mtk_pcie_lane_efuse(9) page from the Kernel API Manual — it’s short, it’s iconic, and it’s literally all about eFuse data for each lane ✨💅

💖 NAME 💖

struct mtk_pcie_lane_efuse — eFuse data for each lane. That’s the whole vibe: one lane, its eFuse data, zero cap 🫶

✨ SYNOPSIS ✨

struct mtk_pcie_lane_efuse {
    u32 tx_pmos;
    u32 tx_nmos;
    u32 rx_data;
    bool lane_efuse_supported;
 };

🎀 Members 🎀

Every field is doing its little thing, and yes, each one matters:

• tx_pmos — TX PMOS impedance selection data. That’s the assignment, periodt.
• tx_nmos — TX NMOS impedance selection data. Same selection-data energy, different field.
• rx_data — RX impedance selection data. RX is having its own data moment.
• lane_efuse_supported — software eFuse data is supported for this lane. It’s a bool, so it’s giving very yes/no main character energy 😌
