| 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 | }; |
