+* Synopsys DesignWare I2C
+
+Required properties :
+
+ - compatible : should be "snps,designware-i2c"
+ - reg : Offset and length of the register set for the device
+ - interrupts : <IRQ> where IRQ is the interrupt number.
+
+Recommended properties :
+
+ - clock-frequency : desired I2C bus clock frequency in Hz.
+
+Example :
+
+ i2c@f0000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "snps,designware-i2c";
+ reg = <0xf0000 0x1000>;
+ interrupts = <11>;
+ clock-frequency = <400000>;
+ };

+This is a list of trivial i2c devices that have simple device tree
+bindings, consisting only of a compatible field, an address and
+possibly an interrupt line.
+
+If a device needs more specific bindings, such as properties to
+describe some aspect of it, there needs to be a specific binding
+document for it just like any other devices.
