dt-bindings: i2c: brcm,kona-i2c: convert to YAML 



Changes during conversion:
  - add used, but previously undocumented SoC-specific compatibles
  - drop references to SoCs that are not upstream
  - add supported clock frequencies

Broadcom Kona Family I2C

=========================



This I2C controller is used in the following Broadcom SoCs:



  BCM11130

  BCM11140

  BCM11351

  BCM28145

  BCM28155



Required Properties

-------------------

- compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c"

- reg: Physical base address and length of controller registers

- interrupts: The interrupt number used by the controller

- clocks: clock specifier for the kona i2c external clock

- clock-frequency: The I2C bus frequency in Hz

- #address-cells: Should be <1>

- #size-cells: Should be <0>



Refer to clocks/clock-bindings.txt for generic clock consumer

properties.



Example:



i2c@3e016000 {

	compatible = "brcm,bcm11351-i2c","brcm,kona-i2c";

	reg = <0x3e016000 0x80>;

	interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>;

	clocks = <&bsc1_clk>;

	clock-frequency = <400000>;

	#address-cells = <1>;

	#size-cells = <0>;

};
