H A Dspi-bus.txt1 SPI (Serial Peripheral Interface) busses
3 SPI busses can be described with a node for the SPI master device
4 and a set of child nodes for each SPI slave on the bus. For this
5 discussion, it is assumed that the system's SPI controller is in
6 SPI master mode. This binding does not describe SPI controllers
9 The SPI master node requires the following properties:
10 - #address-cells - number of cells required to define a chip select
11 address on the SPI bus.
12 - #size-cells - should be zero.
13 - compatible - name of SPI bus controller following generic names
