5 - compatible : should be "wm,wm8505-i2c"
6 - reg : Offset and length of the register set for the device
7 - interrupts : <IRQ> where IRQ is the interrupt number

10Optional properties :
11
12 - clock-frequency : desired I2C bus clock frequency in Hz.
13	Valid values are 100000 and 400000.
14	Default to 100000 if not specified, or invalid value.
