7 title: Peripheral-specific properties for a SPI bus.
10 Many SPI controllers need to add properties to peripheral devices. They could
11 be common properties like spi-max-frequency, spi-cpha, etc. or they could be
12 controller specific like delay in clock or data lines, etc. These properties
13 need to be defined in the peripheral node because they are per-peripheral and

13 SPI busses can be described with a node for the SPI controller device

15 controller may be described for use in SPI master mode or in SPI slave mode,
