platform_device_set_of_node(9)

💅 platform_device_set_of_node 💅

okay bestie, welcome to the Kernel API Manual page for platform_device_set_of_node. we're folding the manual name in right here at the top instead of doing a boring copy-paste header, and honestly? iconic. 🎀

---

🌸 NAME 🌸

platform_device_set_of_node — the function that assigns an OF node to a device 🦋

---

✨ SYNOPSIS ✨

void platform_device_set_of_node (struct platform_device *pdev , struct device_node *np );

---

💖 ARGUMENTS 💖

• pdev — the platform device you're adding the node for 🫶
• np — the new device node ✨

---

🦋 DESCRIPTION 🦋

okay so this one assigns an OF node to this platform device. internally it keeps track of the reference count — no cap, that tracking is part of the vibe. 🔥

big important bestie note: devices created with platform_device_alloc must use this function instead of assigning the node manually. don't try to DIY it, okay? 💅

🚨 and this function must not be called for a platform device that already has a software node as its primary firmware node assigned. that's the hard no. periodt.
