Binding for Broadcom BCM6348/BCM6358 SPI controller



Required properties:

- compatible: must contain one of "brcm,bcm6348-spi", "brcm,bcm6358-spi".

- reg: Base address and size of the controllers memory area.

- interrupts: Interrupt for the SPI block.

- clocks: phandle of the SPI clock.

- clock-names: has to be "spi".

- #address-cells: <1>, as required by generic SPI binding.

- #size-cells: <0>, also as required by generic SPI binding.



Optional properties:

- num-cs: some controllers have less than 8 cs signals. Defaults to 8

  if absent.



Child nodes as per the generic SPI binding.



Example:



	spi@10000800 {

		compatible = "brcm,bcm6368-spi", "brcm,bcm6358-spi";

		reg = <0x10000800 0x70c>;



		interrupts = <1>;



		clocks = <&clkctl 9>;

		clock-names = "spi";



		num-cs = <5>;



		#address-cells = <1>;

		#size-cells = <0>;

	};
