1 Serial Peripheral Interface on Cirrus Logic CL
2
3 Required properties
4 - #address-cells: must be <1>
5 - #size-cells: must be <0>
6 - compatible: should include "cirrus,ep7209-sp
7 - reg: Address and length of one register rang
8 - interrupts: one interrupt line
9 - clocks: One entry, refers to the SPI bus clo
10 - cs-gpios: Specifies the gpio pins to be used
11 See: Documentation/devicetree/bind
12
13 An additional register is present in the syste
14 which is assumed to be in the same device tree
15 as compatible with "cirrus,ep7209-syscon3".
16
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",
30 reg = <0x80002200 0x40>;
31 };
