ti_iodelay_pinconf_set(9)

✨ ti_iodelay_pinconf_set ✨

okay bestie, so this one lives in the Kernel API Manual and it's literally called ti_iodelay_pinconf_set — say that five times fast, i dare you 💅 it's the pin-configuration glow-up function and honestly it's giving main character energy.

---

🌸 NAME 🌸

ti_iodelay_pinconf_set — configure the pin configuration 🎀

---

🦋 SYNOPSIS 🦋

int ti_iodelay_pinconf_set (struct ti_iodelay_device *iod , struct
       ti_iodelay_cfg *cfg );

---

💜 ARGUMENTS 💜

• iod — the iodelay device, your little guy 🫶
• cfg — the configuration, like the outfit it's gonna wear ✨

---

🔥 DESCRIPTION 🔥

So what it does is: update the configuration register as per the TRM, and then lock it up once it's done. periodt. 🔒

⚠️ IMPORTANT NOTE bestie, read this part twice ⚠️ The SoC TRM does recommend doing iodelay programmation only while in Isolation. But — and this is the plot twist 😭 — isolation also implies that every pin on the SoC (including DDR) will be isolated out. So the only benefit you're getting is a glitchless configuration.

However (and here's where it gets iconic), the intent of this driver is purely to support a "glitchy" configuration where applicable. yes, glitchy. on purpose. no cap 💀

---

👑 RETURN 👑

0 in case of success 💖 else an appropriate error value 😭

and that's the whole vibe check 🧚 this cutie came from ./drivers/pinctrl/ti, dated October 2026, and it's filed under ti_iodelay_pinconf_set(9) — mwah, slay, go configure some pins 🍓💅
