💖 pci_host_common_parse_ports(9) 💖

okay bestie, welcome to the Kernel API Manual entry for this little function — it's giving “find the Root Ports and read their vibes” energy, and we're gonna get into it ✨

🎀 NAME 🎀

pci_host_common_parse_ports — Parse Root Port nodes from device tree 🌳

---

✨ SYNOPSIS ✨

int pci_host_common_parse_ports (struct device *dev , struct
pci_host_bridge *bridge );

---

🦋 ARGUMENTS 🦋

• dev — the Device pointer, aka the device bestie in question 🫶
• bridge — the PCI host bridge 💅

---

🌸 DESCRIPTION 🌸

Okay so picture this: it iterates through the child nodes of the host bridge and parses the Root Port properties. And rn? That's currently only reset GPIOs — that's the whole property situation, no cap 👑

0 on success or ports not found, and negative error codes on failure 😭
