[alsa-devel] [PATCH 1/2] mfd: arizona: Add support for INn_MODE register control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Some boards need to set the INn_MODE[1:0] register to change
the input signal patch. This wlf,inmode property is optional.
If present values must be specified by the number of
ARIZONA_MAX_INPUT.

Example:
   - wlf,inmode = <2 0 2 0>;	/* IN1, IN3 use DMIC */
