💅 ufshcd_tx_eqtr(9) — TX EQTR, but make it cute 💅

okay bestie, welcome to the Kernel API Manual entry for ufshcd_tx_eqtr(9) — it’s giving UFS TX equalization energy, and we’re keeping every deet. 🦋

🎀 NAME 🎀

ufshcd_tx_eqtr — Perform TX EQTR procedures with vops callbacks.

✨ SYNOPSIS ✨

int ufshcd_tx_eqtr (struct ufs_hba *hba , struct ufshcd_tx_eq_params
*params , struct ufs_pa_layer_attr *pwr_mode );

🌸 ARGUMENTS 🌸

• hba — per adapter instance
• params — TX EQ parameters data structure to populate
• pwr_mode — target power mode containing gear and rate information

🔥 DESCRIPTION 🔥

This is literally the main entry point for performing TX Equalization Training (EQTR) procedure as defined in UFSCHI v5.0 specification. It serves as a wrapper around __ufshcd_tx_eqtr to provide vops support through the variant operations framework. 🫶

Returns 0 on success, negative error code on failure. 💖
