💅 ufshcd_parse_tx_eq_settings_for_gear(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes it's a real manual page, yes it's from the kernel, and yes we're gonna get through it together. this one's about a little function called ufshcd_parse_tx_eq_settings_for_gear, and honestly? it's giving "quietly doing important UFS work behind the scenes" energy. 🦋

✨ NAME ✨

ufshcd_parse_tx_eq_settings_for_gear — parse static TX EQ DT settings for one gear, no cap

like... it parses. TX EQ settings. from device tree. for exactly one gear. that's the whole job. 🎀

---

🌸 SYNOPSIS 🌸

void ufshcd_parse_tx_eq_settings_for_gear (struct ufs_hba *hba , int gear );

she takes a hba and a gear, and she returns void — as in, she doesn't hand you a value back, she just does the thing and updates stuff internally. main character behaviour fr fr. 👑

---

🫶 ARGUMENTS 🫶

• hba — per adapter instance 💖 (each adapter gets its own lil struct ufs_hba and this is that one)
• gear — the target HS gear ⚡ (which gear's settings we're out here parsing, tyvm)

---

🔥 DESCRIPTION 🔥

okay so here's what she actually reads, and you're gonna want to write these down because they're very literal property names, not vibes:

• txeq-preshoot-gN
• txeq-deemphasis-gN
• and, only when we're talking G6, tx-precode-enable-g6 🌈

those are the device-tree properties she's out here looking at. and then — this is the important part — if all present values are valid, she stores them as static TX Equalization settings for the given gear. 💅

note the wording bestie: if all present values are valid. she's not out here storing half-valid garbage, she checks first. validity check first, storing second. that's the order. periodt. ✨
