I have some patches to that driver and recently I ported those changes to reasonably fresh kernel (4.1-rc7).

There are some changes that are bit distractible to current workings of the driver. (mixer settings related)

Current mainline driver does nothing to connect unused inputs to common mode (datasheet states that that shall be done) and in our testing that had big impact on recorded audio quality.

I've added OF bindings that check which inputs to connect and where and then connect unused inputs to common.

Should I just post my patches here or should I first test them against some other kernel version?
