soctherm_oc_int_init(9)

💖 soctherm_oc_int_init(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — yes this is a section 9 manpage, yes it's from the kernel API manual, and yes we're gonna get through it together. This one's about soctherm_oc_int_init, and it's genuinely not that deep, i promise 🫶

---

🌸 NAME 🌸

soctherm_oc_int_init — the initial enabling of the over current interrupts, periodt 💅

---

✨ SYNOPSIS ✨

int soctherm_oc_int_init (struct fwnode_handle *fwnode , int num_irqs );

like that's the whole signature, she's not complicated 💀

---

🎀 ARGUMENTS 🎀

• fwnode — the devicetree node for soctherm 🌳 (yes, the devicetree node, like the actual fwnode handle for soctherm, that one)
• num_irqs — the number of new interrupt requests 🔥 lowkey just a count, bestie, nothing spooky

---

🦋 DESCRIPTION 🦋

So what does she actually do? She sets the over current interrupt request chip data ✨ that's it, that's the vibe. Not me hyping up a one-line description but here we are 🙈

---

⭐ RETURN ⭐

okay so the return values, pay attention bestie:

• 0 — on success 💚 or also if overcurrent interrupts are not enabled (iconic of her honestly, two ways to win)
• -ENOMEM — out of memory 😭
• irq_base — returned if the function failed to allocate the irqs 💀

ngl, that last one is a little cursed — a non-zero base value coming back as a failure case? but that's literally what the page says so i'm not gonna make stuff up about it fr fr 🫶
