[alsa-devel] [PATCH v4 0/2] ASoC: Add support for DA7217 and DA7218 audio codecs

[Adam Thomson]

This patch set adds DT and ASoC codec driver support for DA7217 and DA7218.

Changes are based against v4.4-rc2 kernel version.

Changes in v4:
 - DT binding updates for unit suffixes (hz, us) at Rob Herring's request.

Changes in v3:
 - At request of Rob Herring, added units suffix to applicable binding names.
 - Add changes for codec Kconfig and Makefile which were somehow missed from
   previous patches.

Changes in v2:
 - Removed Internal LDO voltage selection from DT
 - BiQuad filter coefficients removed from DT, no programmed using mixer
   controls.
 - ALC calibration no longer bypasses regmap cache and instead saves & restores
   registers around procedure, to avoid issues with concurrent regmap access.
 - Removed all unnecessary default settings for mixers in probe.
 - Reporting of mic level detection event to user-space, through input
   VOICECOMMAND key event, removed as not intended for this purpose. Alternative
   solution required as follow up. Event masked off until solution in place.
 - Additional error checking & loggin around mclk usage, in sysclk and
   bias_level functions.
