Serial Peripheral Interface on Cirrus Logic CL-PS71xx, EP72xx, EP73xx
|
|
Required properties
|
- #address-cells: must be <1>
|
- #size-cells: must be <0>
|
- compatible: should include "cirrus,ep7209-spi"
|
- reg: Address and length of one register range
|
- interrupts: one interrupt line
|
- clocks: One entry, refers to the SPI bus clock
|
- cs-gpios: Specifies the gpio pins to be used for chipselects.
|
See: Documentation/devicetree/bindings/spi/spi-bus.txt
|
|
An additional register is present in the system controller,
|
which is assumed to be in the same device tree, with and marked
|
as compatible with "cirrus,ep7209-syscon3".
|
|
Example:
|
|
spi@80000500 {
|
#address-cells = <1>;
|
#size-cells = <0>;
|
compatible = "cirrus,ep7209-spi";
|
reg = <0x80000500 0x4>;
|
interrupts = <15>;
|
clocks = <&clks CLPS711X_CLK_SPI>;
|
};
|
|
syscon3: syscon@80002200 {
|
compatible = "cirrus,ep7209-syscon3", "syscon";
|
reg = <0x80002200 0x40>;
|
};
