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 | }; | ||
