I2C for OMAP platforms | ||
|
||
Required properties : | ||
- compatible : Must be "ti,omap3-i2c" or "ti,omap4-i2c" | ||
- ti,hwmods : Must be "i2c<n>", n being the instance number (1-based) | ||
- #address-cells = <1>; | ||
- #size-cells = <0>; | ||
|
||
Recommended properties : | ||
- clock-frequency : Desired I2C bus clock frequency in Hz. Otherwise | ||
the default 100 kHz frequency will be used. | ||
|
||
Optional properties: | ||
- Child nodes conforming to i2c bus binding | ||
|
||
Note: Current implementation will fetch base address, irq and dma | ||
from omap hwmod data base during device registration. | ||
Future plan is to migrate hwmod data base contents into device tree | ||
blob so that, all the required data will be used from device tree dts | ||
file. | ||
|
||
Examples : | ||
|
||
i2c1: i2c@0 { | ||
compatible = "ti,omap3-i2c"; | ||
#address-cells = <1>; | ||
#size-cells = <0>; | ||
ti,hwmods = "i2c1"; | ||
clock-frequency = <400000>; | ||
}; |
