1I2C for Atmel platforms
2
3Required properties :
4- compatible : Must be "atmel,at91rm9200-i2c", "atmel,at91sam9261-i2c",
5     "atmel,at91sam9260-i2c", "atmel,at91sam9g20-i2c", "atmel,at91sam9g10-i2c"
6     or "atmel,at91sam9x5-i2c"
7- reg: physical base address of the controller and length of memory mapped
8     region.
9- interrupts: interrupt number to the cpu.
10- #address-cells = <1>;
11- #size-cells = <0>;
12- clocks: phandles to input clocks.

14Optional properties:
15- clock-frequency: Desired I2C bus frequency in Hz, otherwise defaults to 100000
16- Child nodes conforming to i2c bus binding
