🌸 NAME 🌸

cxgb4_ptp_adjfine — Adjust frequency of PHC cycle counter

---

✨ SYNOPSIS ✨

int cxgb4_ptp_adjfine (struct ptp_clock_info *ptp , long scaled_ppm );

---

🫶 ARGUMENTS 🫶

• ptp — the ptp clock structure. That’s it, that’s the vibe.
• scaled_ppm — the desired frequency in scaled parts per billion. periodt 💅

---

💅 DESCRIPTION 💅

Okay so this function adjusts the frequency of the PHC cycle counter by the indicated amount from the base frequency. Literally that’s the whole job. 🔥

And for the math girlies: scaled parts per million is ppm with a 16-bit binary fractional field. 🎀

No cap: the argument says “parts per billion” and the description says “parts per million” — both show up in the original, so both stay. 🙈
