💅 drm_of_find_panel_or_bridge(9) — Kernel API Manual ✨

okay bestie, welcome to the drm_of_find_panel_or_bridge(9) page, straight out of the Kernel API Manual 💖 this one's a little deprecated icon, so pay attention, iykyk.

---

🌸 NAME 🌸

drm_of_find_panel_or_bridge — literally returns the connected panel or bridge device 🫶

---

✨ SYNOPSIS ✨

int drm_of_find_panel_or_bridge (const struct device_node *np , int port
, int endpoint , struct drm_panel **panel , struct drm_bridge **bridge
);

---

🎀 ARGUMENTS 🎀

• np — the device tree node that's holding the encoder output ports, main character energy fr 🌈
• port — which port in the device tree node we're looking at 👑
• endpoint — the endpoint in the device tree node, slay 🦋
• panel — pointer to hold the returned drm_panel, and it must not be NULL ⚠️ on success the caller has to call drm_panel_put when they're done with the panel, no cap
• bridge — pointer to hold the returned drm_bridge 💜

---

🔥 DESCRIPTION 🔥

So given a DT node's port and endpoint number, this cutie finds the connected node and returns either the associated struct drm_panel or drm_bridge device ✨ literally that's the whole vibe.

⚠️ okay so important: this function is deprecated and should not be used in new drivers 💀 no exceptions bestie. Use of_drm_get_bridge_by_endpoint instead when you're not looking for a panel, or devm_drm_of_get_bridge otherwise 🫶

It returns zero if successful, or one of the standard error codes if it fails 😭 that's it, that's the deal.
