of_graph_get_port_by_id(9)

🌸 NAME 🌸

okay so this is of_graph_get_port_by_id(9) from the Kernel API Manual — and its whole main-character job is literally: get the port matching a given id. no cap. 💅

✨ SYNOPSIS ✨

bestie, the signature is giving exactly this:

struct device_node * of_graph_get_port_by_id (struct device_node *parent
, u32 id );

🎀 ARGUMENTS 🎀

• parent — pointer to the parent device node 🌳
• id — id of the port 🔢

💖 RETURN 💖

You get a 'port' node pointer with its refcount incremented. The caller has to use of_node_put on it when done — that cleanup step is mandatory, bestie. 🫶
