1Binding for Broadcom BCM6328 High Speed SPI controller
2
3Required properties:
4- compatible: must contain of "brcm,bcm6328-hsspi".
5- reg: Base address and size of the controllers memory area.
6- interrupts: Interrupt for the SPI block.
7- clocks: phandles of the SPI clock and the PLL clock.
8- clock-names: must be "hsspi", "pll".
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@10001000 {
21		compatible = "brcm,bcm6328-hsspi";
22		reg = <0x10001000 0x600>;
23
24		interrupts = <29>;
25
26		clocks = <&clkctl 9>, <&hsspi_pll>;
27		clock-names = "hsspi", "pll";
28
29		num-cs = <2>;
30
31		#address-cells = <1>;
32		#size-cells = <0>;
