Subject: [alsa-devel] [PATCH v2 1/2] mfd: arizona: Add support for INn_Mode register control
Date: Wed, 13 Aug 2014 20:53:13 +0900	[thread overview]
Message-ID: <20140813205313.65bbe343@songinha-Samsung-DeskTop-System> (raw)

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 */
