 3Required properties
 4- #address-cells: must be <1>
 5- #size-cells: must be <0>
 6- compatible: should include "cirrus,ep7209-spi"
 7- reg: Address and length of one register range
 8- interrupts: one interrupt line
 9- clocks: One entry, refers to the SPI bus clock
10- cs-gpios: Specifies the gpio pins to be used for chipselects.

13An additional register is present in the system controller,
14which is assumed to be in the same device tree, with and marked
15as compatible with "cirrus,ep7209-syscon3".
