amba_device_register(9)

💖 amba_device_register(9) 💖

okay so bestie, welcome to the Kernel API Manual — today we're looking at amba_device_register, and honestly? it's giving "let me introduce you to the whole system" main character energy. 🎀

---

✨ NAME ✨

amba_device_register — register an AMBA device 🦋

---

✨ SYNOPSIS ✨

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

like, that's the whole vibe. two args, one int coming back at you. 💅

---

✨ ARGUMENTS ✨

• dev — the AMBA device you're registering. yes, that one. the little guy. 🫶
• parent — the parent memory resource. it's the resource's parent. iconic behaviour honestly. 🌸

---

✨ DESCRIPTION ✨

okay so here's what actually happens, no cap:

it sets up the AMBA device — and while it's doing that, it reads the cell ID if present. (if present!! not guaranteed!! read the room 💀)

then it claims the resource, and after all that it registers the AMBA device with the Linux device manager. slay. ✨

so like, three steps, all of them important:

1. setup the AMBA device (cell ID read if present)
2. claim the resource
3. register the AMBA device with the Linux device manager

periodt. that's the whole function. 🌈

ngl bestie, if you're poking at AMBA devices you're gonna be living in ./drivers/amba/bus.c for a minute. iykyk. 💜
