1 Serial Peripheral Interface on Cirrus Logic CL-PS71xx, EP72xx, EP73xx
2
3 Required properties
4 - #address-cells: must be <1>
5 - #size-cells: must be <0>
6 - compatible: should include "cirrus,ep7209-spi"
7 - reg: Address and length of one register range
8 - interrupts: one interrupt line
9 - clocks: One entry, refers to the SPI bus clock
10 - cs-gpios: Specifies the gpio pins to be used for chipselects.
11 See: Documentation/devicetree/bindings/spi/spi-bus.txt
12
13 An additional register is present in the system controller,
14 which is assumed to be in the same device tree, with and marked
15 as compatible with "cirrus,ep7209-syscon3".

17 Example:
18
19 spi@80000500 {
20 #address-cells = <1>;
21 #size-cells = <0>;
22 compatible = "cirrus,ep7209-spi";
23 reg = <0x80000500 0x4>;
24 interrupts = <15>;
25 clocks = <&clks CLPS711X_CLK_SPI>;
26 };
27
28 syscon3: syscon@80002200 {
29 compatible = "cirrus,ep7209-syscon3", "syscon";
30 reg = <0x80002200 0x40>;
31 };
