1 I2C for OMAP platforms 2 3 Required properties : 4 - compatible : Must be "ti,omap3-i2c" or "ti,omap4-i2c" 5 - ti,hwmods : Must be "i2c<n>", n being the instance number (1-based) 6 - #address-cells = <1>; 7 - #size-cells = <0>; 8 9 Recommended properties : 10 - clock-frequency : Desired I2C bus clock frequency in Hz. Otherwise 11 the default 100 kHz frequency will be used. 12 13 Optional properties: 14 - Child nodes conforming to i2c bus binding 15 16 Note: Current implementation will fetch base address, irq and dma 17 from omap hwmod data base during device registration. 18 Future plan is to migrate hwmod data base contents into device tree 19 blob so that, all the required data will be used from device tree dts 20 file. 21 22 Examples : 23 24 i2c1: i2c@0 { 25 compatible = "ti,omap3-i2c"; 26 #address-cells = <1>; 27 #size-cells = <0>; 28 ti,hwmods = "i2c1"; 29 clock-frequency = <400000>; 30 };
