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>; };
