+
+Required properties:
+
+- compatible : 'manufacturer,model', eg. nuvoton,npct650
+- label : human readable string describing the device, eg. "tpm"
+- linux,sml-base : 64-bit base address of the reserved memory allocated for
+ the firmware event log
+- linux,sml-size : size of the memory allocated for the firmware event log
+
+Example (for OpenPower Systems with Nuvoton TPM 2.0 on I2C)
