+Device-Tree bindings for Juniper connector driver
+
+Required properties:
+ - compatible - Must be one of
+ - "jnx,pic-connector"
+ - "jnx,sib-connector"
+ - "jnx,fpc-connector"
+ - "jnx,cb-connector"
+ - "jnx,psm-connector"
+ - "jnx,fan-connector"
+ - "jnx,mp-connector"
+ - "jnx,fpm-connector"
+ - "jnx,spmb-connector"
+ "simple-bus" must also be specified to facilitate instantiation.
+ - slot - slot number
+
+Optional properties:
+ - assembly-id - Static assembly ID to be used for all adapters.
+ If specified, it is assumed that no ID eeprom is
+ present, and the provided assembly ID will always be
+ used to identify the adapter and the devicetree overlay
+ to load.
+ - presence-detect-gpios - presence detect gpio pin
+ If not provided, card is assumed
+ to be always present.
+ - attention-button-gpios - request button gpio pin
+ - attention-button-ignore - set if kernel shall ignore
+ attention button events
+ - attention-button-holdtime - button hold time in milli-seconds
+ (3s default)
+ - activation-timeout - activation timeout in milli-seconds (10s default)
+ - debounce-interval - debounce interval in milli-seconds
+ (applies to presence detect pin).
+ - power-enable-gpios - power enable gpio pin
+ - power-status-gpios - power status gpio pin (mandatory if
+ power-enable-gpios is provided)
+ - power-enable-timeout - power enable timeout in ms (1s default)
+ - poweron-reset-delay - delay to be applied after poweron in
+ milli-seconds (default none)
+ - reset-gpios - board reset gpio pin
+ - led-green - phandle pointing to green LED
+ - led-red - phandle pointing to red LED
+ - sysfs-linkname - name to be user for the symbolic link under jnx/card
+
+Example node:
+
+ pic0 {
+ compatible = "jnx,pic-connector", "simple-bus";
+ slot = <0>;
+ presence-detect-gpios = <&gpio1 148 0x10013>;
+ attention-button-gpios = <&gpio20 150 0x10013>;
+ power-enable-gpios = <&gpio1 154 0x0>;
+ power-status-gpios = <&gpio1 151 0x3>;
+ reset-gpios = <&gpio1 153 0x10000>;
+ power-enable-timeout = <2000>;
+ debounce-interval = <1>;
+ led-green = <&pic0_green>;
+ led-red = <&pic0_red>;
+ };
