Cool. Can you please split the the patches into following
separate patches:

1. Add minimal board support
2. Add defconfig
3. Add ASoC support
4. Add DSS2 support

Then please run all the patches through scripts/checkpatch.pl --strict
and fix the errors and warnings.

And please make sure things keep compiling through the
all the patches, otherwise git bisect will break.

Cheers,

Tony
