+
+Trusted Platform Module (TPM)
+=============================
+
+The tpm node describes a TPM device present in the platform. It also includes
+event log information.
+
+Required properties
+-------------------
+
+All these properties are consumed by skiboot and the linux kernel (tpm and
+vtpm codes)
+
+::
+
+    compatible :       should have "nuvoton,npct650"
+
+    linux,sml-base:    64-bit base address of the reserved memory allocated for firmware event log.
+                       sml stands for shared memory log.
+
+    linux,sml-size:    size of the memory allocated for firmware event log.
+
+
+Optional properties
+-------------------
+
+::
+
+    status:            indicates whether the device is enabled or disabled. "okay" for
+                       enabled and "disabled" for disabled.
+
+Example
+-------
+
+.. code-block:: dts
+
+    tpm@57 {
+    	reg = <0x57>;
+    	compatible = "nuvoton,npct650", "nuvoton,npct601";
+    	linux,sml-base = <0x7f 0xfd450000>;
+    	linux,sml-size = <0x10000>;
+    	status = "okay";
+    	phandle = <0x10000017>;
+    	linux,phandle = <0x10000017>;
+    };
