I2C for Atmel platforms
|
||
|
|
|
||
|
|
Required properties :
|
||
|
|
- compatible : Must be "atmel,at91rm9200-i2c", "atmel,at91sam9261-i2c",
|
||
|
|
"atmel,at91sam9260-i2c", "atmel,at91sam9g20-i2c", "atmel,at91sam9g10-i2c"
|
||
|
|
or "atmel,at91sam9x5-i2c"
|
||
|
|
- reg: physical base address of the controller and length of memory mapped
|
||
|
|
region.
|
||
|
|
- interrupts: interrupt number to the cpu.
|
||
|
|
- #address-cells = <1>;
|
||
|
|
- #size-cells = <0>;
|
||
|
|
- clocks: phandles to input clocks.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- clock-frequency: Desired I2C bus frequency in Hz, otherwise defaults to 100000
|
||
|
|
- Child nodes conforming to i2c bus binding
|
||
|
|
|
||
|
|

||
|
|
|
||
|
|
