|  | Device tree configuration for the I2C controller on the XLP9xx/5xx SoC | 
|  |  | 
|  | Required properties: | 
|  | - compatible      : should be "netlogic,xlp980-i2c" | 
|  | - reg             : bus address start and address range size of device | 
|  | - interrupts      : interrupt number | 
|  |  | 
|  | Optional properties: | 
|  | - clock-frequency : frequency of bus clock in Hz | 
|  | Defaults to 100 KHz when the property is not specified | 
|  |  | 
|  | Example: | 
|  |  | 
|  | i2c0: i2c@113100 { | 
|  | compatible = "netlogic,xlp980-i2c"; | 
|  | #address-cells = <1>; | 
|  | #size-cells = <0>; | 
|  | reg = <0 0x113100 0x100>; | 
|  | clock-frequency = <400000>; | 
|  | interrupts = <30>; | 
|  | interrupt-parent = <&pic>; | 
|  | }; |
