Required properties:



- compatible: should be "brcm,brcmstb-i2c" or "brcm,brcmper-i2c"

- clock-frequency: 32-bit decimal value of iic master clock freqency in Hz

		   valid values are 375000, 390000, 187500, 200000

		   93750, 97500, 46875 and 50000

- reg: specifies the base physical address and size of the registers



Optional properties :



- interrupts: specifies the interrupt number, the irq line to be used

- interrupt-names: Interrupt name string



Example:



bsca: i2c@f0406200 {

      clock-frequency = <390000>;

      compatible = "brcm,brcmstb-i2c";

      interrupt-parent = <&irq0_intc>;

      reg = <0xf0406200 0x58>;

      interrupts = <0x18>;

      interrupt-names = "upg_bsca";
