[alsa-devel] [PATCH v14 2/8] ASoC: sun4i-codec: Add Mic1 Boost Volume, Mic2 Boost Volume

Wed May 2 23:07:54 CEST 2018
Add Mic1 Boost Volume and Mic2 Boost Volume for Allwinner A10 and Allwinner
A20. Also add support for extra controls to the sun4i_codec_quirks because
the A10 and A20 have Mic1 Boost Volume at different places (likewise for
Mic2 Boost Volume).
