3Required properties:
4- compatible: "lantiq,ase-spi", "lantiq,falcon-spi", "lantiq,xrx100-spi"
5- #address-cells: see spi-bus.txt
6- #size-cells: see spi-bus.txt
7- reg: address and length of the spi master registers
8- interrupts: should contain the "spi_rx", "spi_tx" and "spi_err" interrupt.

11Optional properties:
12- clocks: spi clock phandle
13- num-cs: see spi-bus.txt, set to 8 if unset
14- base-cs: the number of the first chip select, set to 1 if unset.
