  1 WM8741 audio CODEC
  2 
  3 This device supports both I2C and SPI (configured with pin strapping
  4 on the board).
  5 
  6 Required properties:
  7 
  8   - compatible : "wlf,wm8741"
  9 
 10   - reg : the I2C address of the device for I2C, the chip select
 11           number for SPI.
 12 
 13 Optional properties:
 14 
 15   - diff-mode: Differential output mode configuration. Default value for field
 16     DIFF in register R8 (MODE_CONTROL_2). If absent, the default is 0, shall be:
 17     0 = stereo
 18     1 = mono left
 19     2 = stereo reversed
 20     3 = mono right
 21 
 22 Example:
 23 
 24 wm8741: codec@1a {
 25         compatible = "wlf,wm8741";
 26         reg = <0x1a>;
 27 
 28         diff-mode = <3>;
 29 };
