+ - 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.
