| * 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 |
| |
