+Flash device on a Juniper SAM FPGA
+
+These flash chips are found in the PTX series of Juniper routers.
+
+They are regular CFI compatible (Intel or AMD extended) flash chips with
+some special write protect/VPP bits that can be controlled by the machine's
+system controller.
+
+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:
+
+flash_sam {
+	compatible = "jnx,flash-sam";
+	partition at 0 {
+		reg = <0x0 0x400000>;
+		label = "pic0-golden";
+		read-only;
+	};
+};
