1	ARM Freescale DSPI controller
2	
3	Required properties:
4	- compatible : "fsl,vf610-dspi"
5	- reg : Offset and length of the register set for the device
6	- interrupts : Should contain SPI controller interrupt
7	- clocks: from common clock binding: handle to dspi clock.
8	- clock-names: from common clock binding: Shall be "dspi".
9	- pinctrl-0: pin control group to be used for this controller.
10	- pinctrl-names: must contain a "default" entry.
11	- spi-num-chipselects : the number of the chipselect signals.
12	- bus-num : the slave chip chipselect signal number.
13	Example:
14	
15	dspi0@4002c000 {
16		#address-cells = <1>;
17		#size-cells = <0>;
18		compatible = "fsl,vf610-dspi";
19		reg = <0x4002c000 0x1000>;
20		interrupts = <0 67 0x04>;
21		clocks = <&clks VF610_CLK_DSPI0>;
22		clock-names = "dspi";
23		spi-num-chipselects = <5>;
24		bus-num = <0>;
25		pinctrl-names = "default";
26		pinctrl-0 = <&pinctrl_dspi0_1>;
27		status = "okay";
