1Binding for Broadcom BCM6348/BCM6358 SPI controller
2
3Required properties:
4- compatible: must contain one of "brcm,bcm6348-spi", "brcm,bcm6358-spi".
5- reg: Base address and size of the controllers memory area.
6- interrupts: Interrupt for the SPI block.
7- clocks: phandle of the SPI clock.
8- clock-names: has to be "spi".
9- #address-cells: <1>, as required by generic SPI binding.
10- #size-cells: <0>, also as required by generic SPI binding.
11
12Optional properties:
13- num-cs: some controllers have less than 8 cs signals. Defaults to 8
14  if absent.
15
16Child nodes as per the generic SPI binding.

20	spi@10000800 {
21		compatible = "brcm,bcm6368-spi", "brcm,bcm6358-spi";
22		reg = <0x10000800 0x70c>;
23
24		interrupts = <1>;
25
26		clocks = <&clkctl 9>;
27		clock-names = "spi";
28
29		num-cs = <5>;
30
31		#address-cells = <1>;
32		#size-cells = <0>;
33	};
