Kernel-3.10.0-957.el7_ibmvtp

• 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
