This patch enhances PSE callbacks by introducing support for the static port priority feature. It extends interrupt management to handle and report detection, classification, and disconnection events. Additionally, it introduces the pi_get_pw_req() callback, which provides information about the power requested by the Powered Devices. Interrupt support is essential for the proper functioning of the TPS23881 controller. Without it, after a power-on (PWON), the controller will no longer perform detection and classification. This could lead to potential hazards, such as connecting a non-PoE device after a PoE device, which might result in magic smoke.
