3Required properties:
4
5- compatible            : property name that conveys the platform architecture
6                          identifiers, as 'IBM,vtpm'
7- device_type           : specifies type of virtual device
8- interrupts            : property specifying the interrupt source number and
9                          sense code associated with this virtual I/O Adapters
10- ibm,my-drc-index      : integer index for the connector between the device
11                          and its parent - present only if Dynamic
12                          Reconfiguration(DR) Connector is enabled
13- ibm,#dma-address-cells: specifies the number of cells that are used to
14                          encode the physical address field of dma-window
15                          properties
16- ibm,#dma-size-cells   : specifies the number of cells that are used to
17                          encode the size field of dma-window properties
18- ibm,my-dma-window     : specifies DMA window associated with this virtual
19                          IOA
20- ibm,loc-code          : specifies the unique and persistent location code
21                          associated with this virtual I/O Adapters
22- linux,sml-base        : 64-bit base address of the reserved memory allocated
23                          for the firmware event log
24- linux,sml-size        : size of the memory allocated for the firmware event log
