amba_device_add(9)

✨ amba_device_add — bestie edition ✨

okay so this is a page from the Kernel API Manual, and honestly? it's a whole little function and we're gonna learn it together 💖

---

🌸 NAME 🌸

amba_device_add — add a previously allocated AMBA device structure

like, the device struct already exists, you're just... introducing it to the world 🫶

---

🎀 SYNOPSIS 🎀

int amba_device_add (struct amba_device *dev , struct resource *parent );

---

💅 ARGUMENTS 💅

• dev — the AMBA device, allocated by amba_device_alloc. yes bestie, allocated by that one specifically — no cap, that's the vibe ✨
• parent — the resource parent for this device's resources. it's giving "who's your parent resource" energy 👑

---

🔥 DESCRIPTION 🔥

so here's the tea, three whole things happen in here:

1. Claim the resource.
2. Read the device cell ID — but only if it's not already initialized. if you already did it, we're not doing it again, periodt 💀
3. Register the AMBA device with the Linux device manager.

that's it. that's the whole function. lowkey iconic that it does that much in so few words 😭👑
