💖 v4l2_fwnode_device_parse(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the <pink>v4l2_fwnode_device_parse(9) page from the Kernel API Manual — this is literally the function that reads your device's firmware vibes and turns them into actual V4L2 properties. main character energy fr fr 🎀

---

🌸 NAME 🌸

v4l2_fwnode_device_parse — parse fwnode device properties. that's it, that's the whole job description 💅

---

✨ SYNOPSIS ✨

int v4l2_fwnode_device_parse (struct device *dev , struct
v4l2_fwnode_device_properties *props );

like, it takes a dev, it takes a props, and it returns an int. no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

• dev — pointer to struct device. yes, the device. the one with the firmware properties. she's the source of truth 💖
• props — pointer to struct v4l2_fwnode_device_properties, and this is where the parsed property values go to live. think of it as the cute little box you hand over and she fills it up ✨

---

💜 DESCRIPTION 💜

so here's the tea: this function parses and validates the V4L2 fwnode device properties straight from the firmware interface. reads them, checks them, and then fills the struct v4l2_fwnode_device_properties that the caller handed in. caller provides the box, function provides the contents. iconic division of labour 👑

---

🔥 RETURN 🔥

• % 0 on success — slay, everything parsed and validated, we love to see it 💅
• -EINVAL if a parsed property value is not valid — nope, firmware said something cursed, the vibe check failed 💀

real talk: if you see -EINVAL, one of the property values coming out of firmware wasn't valid. don't ignore it, bestie 😭
