STRUCT V4L2_FWNODE_LINK(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual ✨ this page is all about struct v4l2_fwnode_link(9) — literally a link between two endpoints 💅 no cap, it's the lil struct that keeps track of who's connected to who on the firmware-node side. iykyk 🦋

✨ SYNOPSIS ✨

       struct v4l2_fwnode_link {
           struct fwnode_handle *local_node;
           unsigned int local_port;
           unsigned int local_id;
           struct fwnode_handle *remote_node;
           unsigned int remote_port;
           unsigned int remote_id;
        };

bestie, here's the rundown on every single field — don't skip, they all matter 💖

• local_node — pointer to device_node of this endpoint 🌸 like, this is the local side's node pointer, periodt.
• local_port — identifier of the port this endpoint belongs to 🎀
• local_id — identifier of the id this endpoint belongs to ✨
• remote_node — pointer to device_node of the remote endpoint 💫 the other side's node pointer, no cap.
• remote_port — identifier of the port the remote endpoint belongs to 🦋
• remote_id — identifier of the id the remote endpoint belongs to 💜
