wm8751: document and fix audiohw settings

2016-12-12T12:12:15+00:00

Document 3D depth range. Fix mismatch in recording volume: the displayed volume
is completely off the chart

Change-Id: I4c363f369e5d72f332391a6f96457b4e450404f9

Fix various reds. Some includes needed fixup.

Fix audio on m:robe 100.

2013-12-17T19:20:00+00:00

Tested on different revisions and it works reliably.

Change-Id: Ic710236247a17f516c8561429f2da5c9684341b9

Do some cleanup, adjustment and a couple fixes to recent sound changes.

* SOUND_x enum can be generated by audiohw_settings.h along with settings
entries and sound_val2phys.

* VOLUME_MIN and VOLUME_MAX are no longer necessary within sound.c. If
you need them, they are for target-defined purposes.

* Fix up SDL volume implementation in sdl.c. Move sim volume calculation
code to pcm-sdl.c.

* Min trigger tresholds were based upon VOLUME_MIN for some reason.
These setting have nothing to do with playback volume. Since it is no
longer present, set these at -89dB which is the minimum peak meter
sensitivity setting.

* Fix an oversight in wm8758.c. I forgot to add the dB->register
conversion to audiohw_set_volume.

Straighten out the mad twisted state of sound.c and related areas.

This is going right in since it's long overdue. If anything is goofed,
drop me a line or just tweak it yourself if you know what's wrong. :-)

Make HW/SW codec interface more uniform when emulating HW functionality
on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to-
DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX"
APIs are all in sound.c with none in DSP code any longer.

Reduce number of settings definitions needed by each codec by providing
defaults for common ones like balance, channels and SW tone controls.

Remove need for separate SIM code and tables and add virtual codec header
for hosted targets.

WM8750: Extend recording gain range.

2012-01-25T08:31:34+00:00

Use two stage amplification (PGA gain and digital stage gain)
combined to extend recgain range to -17.25 +60.0dB.

Change-Id: I4df8af801730b7efb2d35096de077ba31d331222

Add missing includes found using -Wmissing-declarations.

MPIO HD300: vastly improve sound quality. This unfortunately means reverting r28797 which introduced poping noise
