1 | * Device Tree Bindings for IBM Virtual Trusted Platform Module(vtpm) |
| 2 | ||
| 3 | Required 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 | |
| 25 | ||
