STRUCT UFSHCD_TX_EQ_SETTINGS(9)

💜 struct ufshcd_tx_eq_settings(9) 💜

okay so this is a page straight out of the Kernel API Manual bestie, and it's all about one lil struct that babysits your TX equalization settings ✨ ngl it's short but it's iconic.

---

🌸 NAME 🌸

struct ufshcd_tx_eq_settings — literally the TX Equalization settings, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

struct ufshcd_tx_eq_settings {
    u8 preshoot;
    u8 deemphasis;
    u8 fom_val;
    bool precode_en;
 };

like look at her 💅 four members, zero drama, fully slaying.

🦋 Members 🦋

• preshoot — the PreShoot value, yes that's the whole description and honestly she said what she said 💖
• deemphasis — the DeEmphasis value 🫶
• fom_val — the Figure-of-Merit value, and like... where does it come from? it gets read out from RX_FOM and specifically Bit[6:0] 👑 so yeah, seven bits of pure merit, no cap.
• precode_en — a bool flag that tells you whether pre-coding needs to be enabled or not 😭 it's giving "yes/no main character energy".
