This patch series introduces per-port device tree configuration with poe class restrictions. Also adds optional reset/shutdown gpios. Tested with hw poe tester: - Auto mode tested with no per-port DT settings as well as explicit port DT ti,class=4. Tested that no IRQ is required in this case. - Semi-Auto mode with class restricted to 0, 1, 2 or 3. IRQ required. - Tested current cut-offs in Semi-Auto mode. - On/off by default setting tested for both Auto and Semi-Auto modes. - Tested fully disabling the ports in DT. - Tested with both reset and ti,ports-shutdown gpios defined, as well as with reset only, as well as with neither reset nor shutdown.
