* 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 : <a b> 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;
};
