* I2C Required properties : - device_type : Should be "i2c" - reg : Offset and length of the register set for the device Recommended properties : - compatible : Should be "fsl-i2c" for parts compatible with Freescale I2C specifications. - interrupts : where a is the interrupt number and b is a field that represents an encoding of the sense and level information for the interrupt. This should be encoded based on the information in section 2) depending on the type of interrupt controller you have. - interrupt-parent : the phandle for the interrupt controller that services interrupts for this device. - dfsrr : boolean; if defined, indicates that this I2C device has a digital filter sampling rate register - fsl5200-clocking : boolean; if defined, indicated that this device uses the FSL 5200 clocking mechanism. Example : i2c@3000 { interrupt-parent = <40000>; interrupts = <1b 3>; reg = <3000 18>; device_type = "i2c"; compatible = "fsl-i2c"; dfsrr; };
