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
