rockbox/firmware/export/wm8985.h, branch working

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

2013-04-23T00:38:17+00:00

* 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.

Submit FS#11240 by Raphael Jakse. Allows to reduce volume on WM8985 to -89 dB (e.g. used for Cowon D2). Below -57 dB the line out is affected. The manual is updated accordingly.

D2: Enable FM radio (based on FS#10035 by Michael Burtin with some changes by myself). Also updates the LV24020 driver to add optional logf debugging.

add AUDIOHW_CAP for bass cutoff and treble cut off and fix a wrong ifdef for simulator.

* introduce AUDIOHW_CAPS to define which audio codec can do what kind of operations in hw, e.g. setting bass

2008-04-28T08:37:18+00:00

* added documentation why and when we need the software based prescaler
* implement audiohw_set_bass and audiohw_set_treble for mas35xx
* clean up sound_set_bass and sound_set_treble
* simplify some #ifdef logic
* fix special handling of WM8751 - looking for tester :)

D2: Beginnings of a WM8985 driver (based on WM8758, using EQ1 and EQ5 as HW treble/bass). Untested, but harmless.
