+* Device tree bindings for Juniper's PTX1K boot FPGA MFD driver
+
+The device supports a hardware watchdog, a flash MTD device and
+a hwmon sensor device. The bindings of those drivers are described
+in the jnx-ptx1kbf-wdt, jnx-ptx1kbf-mtd and jnx-ptx1kbf-hwmon documents.
+
+Required properties:
+
+- compatible:		"ptx1k-bootfpga"
+
+- reg:			contains offset/length value for device state control
+			registers space.
+
+Example:
+
+bootfpga@...00 {
+	compatible = "jnx,ptx1k-bootfpga";
+	reg = <0x10000 0x100>;
+
+	wdt {
+		compatible = "jnx,ptx1kbf-wdt";
+		/* no properties required */
+	};
+
+	mtd {
+		compatible = "jnx,ptx1kbf-mtd";
+		/* use the full device */
+	};
+
+	hwmon {
+		compatible = "jnx,ptx1kbf-hwmon";
+		/* no properties required */
+	};
+};
