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

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 */

Might be better to allow the device tree to be shorter than the array in pdata, should this get expanded on future devices.
