1Broadcom Kona Family I2C
2=========================
3
4This I2C controller is used in the following Broadcom SoCs:
5
6  BCM11130
7  BCM11140
8  BCM11351
9  BCM28145
10  BCM28155

12Required Properties
13-------------------
14- compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c"
15- reg: Physical base address and length of controller registers
16- interrupts: The interrupt number used by the controller
17- clocks: clock specifier for the kona i2c external clock
18- clock-frequency: The I2C bus frequency in Hz
19- #address-cells: Should be <1>
20- #size-cells: Should be <0>
