zynqmp_runtime_resume(9)

💖 NAME 💖

zynqmp_runtime_resume — the runtime resume method for the SPI driver, bestie ✨

This page lives in the Kernel API Manual (section 9), and it's all about one lil function that wakes your SPI driver back up. 🦋

---

🌸 SYNOPSIS 🌸

int zynqmp_runtime_resume (struct device *dev );

That's the whole vibe. One function, one argument, returns an int. Simple queen behavior 👑

---

🎀 ARGUMENTS 🎀

• dev — the address of the platform_device structure 🫶 like, hand her the device struct and she'll take it from there

---

✨ DESCRIPTION ✨

Okay so literally what this does: this function enables the clocks ⏰💅

That's it, that's the whole description. She wakes up, she turns the clocks on, she's iconic, she leaves. No cap. 🔥

---

⭐ RETURN ⭐

• 0 on success 🎉
• an error value on error 😭

So bestie, always check the return. Zero means slay, anything else means the vibe check failed. 💀
