+ - input-use: Array of input pins used by the driver, shall contain 6 values.
+    Pin input order is lin1, rin1, lin2, rin2, lin3, rin3.
+    Each value can hold value for primary function in low nybble (x & 0xf) or
+    value for secondary function in high nybble (x & 0xf0).
+    Possible values are:
+    0 = input not in use
+    1 = input connected with 10k Ohm (0dB)
+    2 = input connected with 20k Ohm (-6dB)
+    3 = input connected with 40k Ohm (-12dB)
+    If value for pin is 0, driver connects the pin weakly to common mode
 
 Optional properties:
  - reset-gpios: Reset-GPIO phandle with args as described in gpio/gpio.txt
  - clocks/clock-names: Clock named 'mclk' for the master clock of the codec.
    See clock/clock-bindings.txt for information about the detailed format.

+ - cmode: Array of common mode setup data when channels are used in single

+    Parameter order is cmode1, cmode2.
+    Low nybble holds config for left channel and high nybble holds config for
