1 Broadcom stb bsc iic master controller
5 - compatible: should be "brcm,brcmstb-i2c" or "brcm,brcmper-i2c"
6 - clock-frequency: 32-bit decimal value of iic master clock freqency in Hz
7 valid values are 375000, 390000, 187500, 200000
8 93750, 97500, 46875 and 50000
9 - reg: specifies the base physical address and size of the registers
13 - interrupt-parent: specifies the phandle to the parent interrupt controller
14 this one is cascaded from
15 - interrupts: specifies the interrupt number, the irq line to be used
16 - interrupt-names: Interrupt name string
