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>;
|
|
};
