void drm_aux_hpd_bridge_notify (struct device *dev , enum
       drm_connector_status status );

---

🦋 ARGUMENTS 🦋

• dev — the device created for the HPD bridge. That's the one holding down the bridge side of things 💅

🔥 DESCRIPTION 🔥

This function is a wrapper around drm_bridge_hpd_notify, and its whole job is to report hot plug detection events for bridges that were created via drm_dp_hpd_bridge_register. It's giving “little bridge messenger” energy 😭✨

This function shall be called in a context that can sleep. Like, that's the rule, bestie — it's literally in the description, so respect it 🫶
