4 and a set of child nodes for each SPI slave on the bus. The system's SPI
5 controller may be described for use in SPI master mode or in SPI slave mode,
8 The SPI controller node requires the following properties:
9 - compatible - Name of SPI bus controller following generic names
12 In master mode, the SPI controller node requires the following additional
14 - #address-cells - number of cells required to define a chip select
15 address on the SPI bus.
16 - #size-cells - should be zero.
