Samsung YP-R1 target port

2014-02-05T08:56:21+00:00

This is the basic port to the new target Samsung
YP-R1, which runs on a similar platform as YP-R0.
Port is usable, although there are still
some optimizations that have to be done.

Add missing kernel.h includes (hopefully all of them).

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.

Gigabeat S/i.MX31/wm8978: Clean up clocking information in the general wmcodec/pcm drivers and move it to the target's wmcodec/i2s files.

WM8978: Turn off AMUTE since it can cause annoying clicking with audio that produces runs of zeros (esp. emulators and synths) and makes it worse when starting/stopping pcm.

WM8978: sound.c weirdness strikes again. Prescaler values have to be in centibels.

Gigabeat S: Turn off hardware effects (tone and 3d) when doing digital loopback for FM recording otherwise the signal and levels are poorly represented in monitoring (can't just do ADC->DAC for general FM and get voice too). Some tweaking to input setup to improve gain a tiny bit. A little bit quieter startup too.

Gigabeat S: Fully enable access to hardware tone controls and 3-D effect feature. Under the hood, it's designated a hardware equalizer since it is one. Implement code framework for hardware EQ in general. Menu aspect is well abstracted and so the UI and strings can be changed around if taste doesn't quite suit. So far the emphasis is distinction of the UI labelling from the software EQ so that it's clear the settings are for a different thing.
