🌸 NAME 🌸

okay so bestie, iort_register_domain_token — it registers a domain token along with its related ITS ID and base address into the list, and that list is literally where we go to get it back later on. it's giving save-your-spot energy fr fr 💅

✨ SYNOPSIS ✨

int iort_register_domain_token (int trans_id , phys_addr_t base , struct fwnode_handle *fw_node );

like, that's the whole signature, no cap 🫶

🎀 ARGUMENTS 🎀

• trans_id — the ITS ID. that's it, that's the whole vibe.
• base — the ITS base address. iconic, holds the location info 💖
• fw_node — the domain token. the little star of the show ⭐

🌈 RETURN 🌈

• 0 on success — slay, we did it 👑
• -ENOMEM if there's no memory when allocating the list element — literally cannot even, the allocator ran dry 😭
