- +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>;
- + };
