As we claim to support device tree for mach-omap2, we should have the necessary flags in the driver to make it usable. Cc: linux-i2c@vger.kernel.org Acked-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Tony Lindgren <tony@atomide.com>

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>;
|
|
};
