   1 * Freescale SGTL5000 Stereo Codec
   2
   3 Required properties:
   4 - compatible : "fsl,sgtl5000".
   5
   6 - reg : the I2C address of the device
   7
   8 - clocks : the clock provider of SYS_MCLK
   9
  10 - VDDA-supply : the regulator provider of VDDA
  11
  12 - VDDIO-supply: the regulator provider of VDDIO
  13
  14 Optional properties:
  15
  16 - VDDD-supply : the regulator provider of VDDD
  17
  18 - micbias-resistor-k-ohms : the bias resistor to be used in kOmhs
  19         The resistor can take values of 2k, 4k or 8k.
  20         If set to 0 it will be off.
  21         If this node is not mentioned or if the value is unknown, then
  22         micbias resistor is set to 4K.
  23
  24 - micbias-voltage-m-volts : the bias voltage to be used in mVolts
  25         The voltage can take values from 1.25V to 3V by 250mV steps
  26         If this node is not mentioned or the value is unknown, then
  27         the value is set to 1.25V.
