* 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;
|
||
|
|
};
