+Flash device on a PTX1K Boot FPGA
+
+These flash chips are found in the PTX series of Juniper routers.
+
+Required properties:
+- compatible : must be "jnx,flash-sam"
+
+Optional properties:
+- reg : memory address for the flash chip, note that this is not
+required since usually the device is a subdevice of the SAM MFD
+driver which fills in the register fields.
+
+For the rest of the properties, see mtd-physmap.txt.
+
+The device tree may optionally contain sub-nodes describing partitions of the
+address space. See partition.txt for more detail.
+
+Example:
+
+ptx1kbf_mtd {
+	compatible = "jnx,ptx1kbf-mtd";
+	/* usually the whole flash is used */
+};
