7 title: SPI Controller Common Properties
13   SPI busses can be described with a node for the SPI controller device
14   and a set of child nodes for each SPI slave on the bus. The system SPI
15   controller may be described for use in SPI master mode or in SPI slave mode,
20     pattern: "^spi(@.*|-([0-9]|[1-9][0-9]+))?$"
