as3514: fix bug in volume management on AS3543 targets which are not AS3525v2

2016-02-12T23:04:33+00:00

Some old code made the assumption that CONFIG_CPU == AS3525v2 if and only if
HAVE_AS3543, which is not true on targets like the Samsung YP-R0. This fixes
several issues on such targets like a huge volume gap between -39dB and -40dB
and a volume artificially capped at -72dB instead of -82dB.

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.

2013-04-15T16:02:05+00:00

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.

AMSv2: add proper definitions for charge current

ypr0: Remove last #ifdef in as3514.

It's now using completely the same driver as Sansa daps.
This also increases the volume range.

Initial commit of the Samsung YP-R0 port.

2011-12-24T11:56:46+00:00

This port is a hybrid native/RaaA port. It runs on a embedded linux system,
but is the only application. It therefore can implement lots of stuff that
native targets also implement, while leveraging the underlying linux kernel.

The port is quite advanced. User interface, audio playback, plugins work
mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page).

Included in utils/ypr0tools are scripts and programs required to generate
a patched firmware. The patched firmware has the rootfs modified to load
Rockbox. It includes a early/safe USB mode.

This port needs a new toolchain, one that includes glibc headers and libraries.
rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may
also work.

Most of the initial effort is done by Lorenzo Miori and others (on ABI),
including reverse engineering and patching of the original firmware,
initial drivers, and more. Big thanks to you.

Merry christmas to ypr0 owners! :)

Sansa AMS/AMSv2: analog front-end register CVDD/DCDC3 doesn't exist in AMSv2, so don't modify it

Commit FS#12111 by Stephan Grossklass. Disables output mixer auto gain control on AMSv2. Should fix occasional distortion reported when running the player at very high output levels (e.g. at or above 0dB).
