Hi,

this is the seventh version of the patch set that adds inputs to sun4i-codec.

Changes compared to v6 are:
 - preparation for different A20, A10 controls is now in an extra patch.
 - all register definitions are now at the top
 - sun7i-specific things (A20-specific things) are now less grouped-together.

The patches are on top of the branch "sunxi-next" in 
<git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git>.

Regards,
   Danny

  sun4i-codec: Add FM, Line and Mic inputs
  sun4i-codec: make it possible to use different codec_widgets for A10 and A20.
