rzv2h_dphy_find_timings_val(9)

✨ rzv2h_dphy_find_timings_val(9) ✨

okay so this is a page straight out of the Kernel API Manual, and bestie, it's a little function that does a very specific little job in the Renesas MIPI DSI world 💅

---

🌸 NAME 🌸

rzv2h_dphy_find_timings_val — find the timing parameter value from lookup tables 🎀

---

🦋 SYNOPSIS 🦋

u16 rzv2h_dphy_find_timings_val (unsigned long freq , u8 index );

like, that's the whole signature. short and iconic 👑

---

💖 ARGUMENTS 💖

• freq — the input frequency, in Hz. that's it, that's the unit, don't come at me with kHz 🙈
• index — the index that picks which timing parameter table you're digging into (peep enum rzv2h_dsi_timing_idx for the lineup) 🍓

---

⭐ DESCRIPTION ⭐

so what it actually does: it grabs the timing table for the parameter you asked for, hunts down the frequency-range entry that matches, and hands back the register value you're supposed to program. literally that simple, no cap ✨

and here's the formula, copy it exactly bestie:

register_value = timings->base_value + table_index

slay. that's the whole vibe 💜

---

🔥 NOTE 🔥

heads up, this part matters: the frequency table entries are stored as small integers, in units of 10. so you can't just use them raw — you convert like this:

threshold_in_hz = (unsigned long)table_entry * 10 * MEGA

the * 10 * MEGA is doing the heavy lifting, don't skip it 🫶

---

👑 RETURN 👑

it returns the timing register value that gets programmed into the hardware. one value, that's your whole answer 💀✨
