Binding for Broadcom BCM6328 High Speed SPI controller
Required properties:
- compatible: must contain of "brcm,bcm6328-hsspi".
- reg: Base address and size of the controllers memory area.
- interrupts: Interrupt for the SPI block.
- clocks: phandles of the SPI clock and the PLL clock.
- clock-names: must be "hsspi", "pll".
- #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@10001000 {
compatible = "brcm,bcm6328-hsspi";
reg = <0x10001000 0x600>;
interrupts = <29>;
clocks = <&clkctl 9>, <&hsspi_pll>;
clock-names = "hsspi", "pll";
num-cs = <2>;
#address-cells = <1>;
#size-cells = <0>;
};
