v4l2_fwnode_connector_parse(9)

💅 v4l2_fwnode_connector_parse — the kernel API manual, bestie edition ✨

Okay so this is a page from the Kernel API Manual, and it's all about v4l2_fwnode_connector_parse. Think of it as the glow-up ritual for a struct v4l2_fwnode_connector — you hand it a fwnode, it fills in the vibe, periodt. 🫶

✨ NAME ✨

v4l2_fwnode_connector_parse — initialize the struct v4l2_fwnode_connector, bestie. That's literally the whole job. 🎀

🌸 SYNOPSIS 🌸

int v4l2_fwnode_connector_parse (struct fwnode_handle *fwnode , struct
v4l2_fwnode_connector *connector );

No cap, that's the exact signature, character for character. 💖

🦋 ARGUMENTS 🦋

• fwnode — pointer to the subdev endpoint's fwnode handle where the connector is connected to, or to the connector endpoint fwnode handle. Either one, your call, it's giving flexible. ✨
• connector — pointer to the V4L2 fwnode connector data structure. This is the main character getting filled in. 👑

💜 DESCRIPTION 💜

So the whole point: this function fills the struct v4l2_fwnode_connector with the connector type, the label, and all the enum v4l2_connector_type specific connector data. Slay. 🌈

The label is optional, so if nobody found one, it's set to NULL. Lowkey that's just how it is. And the function initialize the links to zero — if you want to actually add links to the connector, that's a whole separate thing, you do it by calling v4l2_fwnode_connector_add_link. iykyk. 💅

Heads up bestie: the memory allocated for the label must be freed when no longer needed. Freeing it is done by v4l2_fwnode_connector_free. Not me letting you forget this and leak memory 😭 — free it, fr fr.

⭐ RETURN ⭐

• 0 on success, or a negative error code on failure. Simple as that. 🎀
• -EINVAL if fwnode is invalid — vibe check failed, the fwnode is not it. 💀
• -ENOTCONN if the connector type is unknown or the connector device can't be found. Like, nobody's home. 🙈
