Add inputs to sun4i-codec: - FM-in Left and Right - Line-in Left and Right - Mic1-in - Mic2-in
Signed-off-by: Danny Milosavljevic dannym+a@scratchpost.org Tested-by: Danny Milosavljevic dannym+a@scratchpost.org (ONLY ON A20!) --- Hi,
this is the sixth version of the patch that adds inputs to sun4i-codec.
Changes compared to v5 are: - Mic preamplifier special cases for A20 and A10 now are now not icky: There are two different _widget arrays and the probe() function now selects the right one to pass to snd_soc_register_codec() unmodified. - sun7i-specific things (A20-specific things) are now grouped together.
I successfully tested it again on an A20 board using alsamixer, headphones, a radio and my ears. Note that because of missing capturing support I tested only the mixing, for Mic, Line, and FM.
The patches are on top of git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git, branch "sunxi/for-next".
