Such cages typically have a number of pins connect to GPIOs, so you can tell when there is a module in the cage, enable the transmit laser, know if light is entering the module from the link peer, etc. sfp2: sfp { compatible = "sff,sfp"; i2c-bus = <&sfp_i2c>; los-gpios = <&cps_gpio1 28 GPIO_ACTIVE_HIGH>; mod-def0-gpios = <&cps_gpio1 27 GPIO_ACTIVE_LOW>; pinctrl-names = "default"; pinctrl-0 = <&cps_sfpp0_pins>; tx-disable-gpios = <&cps_gpio1 29 GPIO_ACTIVE_HIGH>; tx-fault-gpios = <&cps_gpio1 26 GPIO_ACTIVE_HIGH>; }; Andrew
