* Freescale Inter IC (I2C) and High Speed Inter IC (HS-I2C) for i.MX
|
||
|
|
||
|
Required properties:
|
||
|
- compatible : Should be "fsl,<chip>-i2c"
|
||
|
- reg : Should contain I2C/HS-I2C registers location and length
|
||
|
- interrupts : Should contain I2C/HS-I2C interrupt
|
||
|
|
||
|
Optional properties:
|
||
|
- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
|
||
|
The absence of the propoerty indicates the default frequency 100 kHz.
|
||
|
|
||
|
Examples:
|
||
|
|
||
|
i2c@83fc4000 { /* I2C2 on i.MX51 */
|
||
|
compatible = "fsl,imx51-i2c", "fsl,imx1-i2c";
|
||
|
reg = <0x83fc4000 0x4000>;
|
||
|
interrupts = <63>;
|
||
|
};
|
||
|
|
||
|
i2c@70038000 { /* HS-I2C on i.MX51 */
|
||
|
compatible = "fsl,imx51-i2c", "fsl,imx1-i2c";
|
||
|
reg = <0x70038000 0x4000>;
|
||
|
interrupts = <64>;
|
||
|
clock-frequency = <400000>;
|
||
|
};
