-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@...06200 {
-      clock-frequency = <390000>;
