+* Device tree bindings for Juniper's PTXPMB Extended CPLD FPGA MFD driver
+
+The device supports a gpio block which is described in the
+jnx-gpio-ptxpmb-ext-cpld document.
+
+Required properties:
+
+- compatible: "jnx,ptxpmb-ext-cpld"
+
+- reg: contains offset/length value for device state control
+ registers space.
+
+Optional properties:
+
+- interrupts: The interrupt line(s) the /IRQ signal(s) for the device is
+ connected to.
+
+- interrupt-parent: The parent interrupt controller.
+
+Example:
+
+ext-cpld@1,0 {
+ compatible = "jnx,ptxpmb-ext-cpld";
+ reg = <0x1 0 0x1000>;
+ interrupt-parent = <&mpic>;
+ interrupts = <7 2>, <8 2>;
+
+ gpio_ext_cpld: cpld-ext-gpio {
+ compatible = "jnx,gpio-ptxpmb-ext-cpld";
+ #gpio-cells = <2>;
+ #interrupt-cells = <2>;
+ gpio-controller;
+ interrupt-controller;
+ };
+};
