+* 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;
+       };
+};
