+-Broadcom stb bsc iic master controller
+-
+-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";
