+* Device Tree Bindings for IBM Virtual Trusted Platform Module(vtpm)
+
+Required properties:
+
+- compatible            : property name that conveys the platform architecture
+                          identifiers, as 'IBM,vtpm'
+- device_type           : specifies type of virtual device
+- interrupts            : property specifying the interrupt source number and
+                          sense code associated with this virtual I/O Adapters
+- ibm,my-drc-index      : integer index for the connector between the device
+                          and its parent - present only if Dynamic
+                          Reconfiguration(DR) Connector is enabled
+- ibm,#dma-address-cells: specifies the number of cells that are used to
+                          encode the physical address field of dma-window
+                          properties
+- ibm,#dma-size-cells   : specifies the number of cells that are used to
+                          encode the size field of dma-window properties
+- ibm,my-dma-window     : specifies DMA window associated with this virtual
+                          IOA
+- ibm,loc-code          : specifies the unique and persistent location code
+                          associated with this virtual I/O Adapters
+- 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
