+* 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@10000 {
+ 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 */
+ };
+};
