| I2C for OMAP platforms |
| |
| Required properties : |
| - compatible : Must be "ti,omap2420-i2c", "ti,omap2430-i2c", "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>; |
| }; |
