|
||
|
|
|
||
|
|
Required properties :
|
||
|
|
- compatible : Must be "atmel,at91rm9200-i2c", "atmel,at91sam9261-i2c",
|
||
|
|
"atmel,at91sam9260-i2c", "atmel,at91sam9g20-i2c", "atmel,at91sam9g10-i2c",
|
||
|
|
"atmel,at91sam9x5-i2c", "atmel,sama5d4-i2c" or "atmel,sama5d2-i2c".
|
||
|
|
- reg: physical base address of the controller and length of memory mapped
|
||
|
|
region.
|
||
|
|
- #address-cells = <1>;
|
||
|
|
- #size-cells = <0>;
|
||
|
|
- clocks: phandles to input clocks.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- clock-frequency: Desired I2C bus frequency in Hz, default value is 100000.
|
||
|
|
- Child nodes conforming to i2c bus binding.
|
||
|
|
|
||
|
|
Examples :
|
||
|
|
|
||
|
|
i2c0: i2c@f8028000 {
|
||
|
|
compatible = "atmel,sama5d2-i2c";
|
||
|
|
reg = <0xf8028000 0x100>;
|
||
|
|
#address-cells = <1>;
|
||

|
#size-cells = <0>;
|
||
|
|
clocks = <&twi0_clk>;
|
||
|
|
clock-frequency = <100000>;
|
||
|
