* 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.
