rockchip_pcie_parse_host_dt(9)

💖 rockchip_pcie_parse_host_dt(9) 💖

okay so real talk, this is a page straight out of the Kernel API Manual and it's about one little function that reads the Device Tree for a Rockchip PCIe host controller. she's short, she's sweet, she's giving "one job and she does it" energy. let's get into it 🎀

---

✨ NAME ✨

rockchip_pcie_parse_host_dt — literally just Parse Device Tree. that's the whole gig. no cap. 🦋

---

🌸 SYNOPSIS 🌸

int rockchip_pcie_parse_host_dt(struct rockchip_pcie *rockchip);

like… look at her. one argument. returns an int. main character energy fr fr 👑

---

💅 ARGUMENTS 💅

• rockchip — the PCIe port information. that's it, that's the description the manpage gives us, and we are respecting it. it's a struct rockchip_pcie * and it's carrying all the port info this function needs to do its thing. 🫶

---

⭐ RETURN ⭐

bestie. the original page leaves this section completely empty. no return values listed, no description, nada. so we are not gonna sit here and invent lore 😭 — the only thing we know for sure is the signature says it hands back an int. that's the tea. 💀

---

🌈 SEE ALSO 🌈

these are the receipts, go look at them yourself iykyk:

• the kernel file ./drivers/pci/controller/pcie-rockchip-host.c — that's where all the actual code lives 🔥
• rockchip_pcie_host_init_port(9) — the sibling function, probably what you call after this one has done its parsing thing ✨

---

a gentle reminder: this page tells you literally nothing about what happens on a failure, so don't @ me, @ the source file 💖

---

and that's the whole page!! short and iconic, just like her 🧚
