* Marvell Armada 3700 SPI Controller
|
|
|
|
Required Properties:
|
|
|
|
- compatible: should be "marvell,armada-3700-spi"
|
|
- reg: physical base address of the controller and length of memory mapped
|
|
region.
|
|
- interrupts: The interrupt number. The interrupt specifier format depends on
|
|
the interrupt controller and of its driver.
|
|
- clocks: Must contain the clock source, usually from the North Bridge clocks.
|
|
- num-cs: The number of chip selects that is supported by this SPI Controller
|
|
- #address-cells: should be 1.
|
|
- #size-cells: should be 0.
|
|
|
|
Example:
|
|
|
|
spi0: spi@10600 {
|
|
compatible = "marvell,armada-3700-spi";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
reg = <0x10600 0x5d>;
|
|
clocks = <&nb_perih_clk 7>;
|
|
interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
|
|
num-cs = <4>;
|
|
};
