+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>;
+ status = "disabled";
+};
+
+syscon3: syscon@80002200 {
+ compatible = "cirrus,ep7209-syscon3", "syscon";
+ reg = <0x80002200 0x40>;
+};
