* as3543: fix audio gap when switching from dac to line-in/recordingAmaury Pouly2016-08-29
| | | | | | | | | | | | | | | | Also clarity parts of the code. The old code suffered from two defects: - it was very unclear because it made changes to whole registers (using as3514_write) instead of fields (using as3514_set/clear/write_masked). Also the routing code was spread accross several functions which made it hard to follow. - it did not properly reroute audio on monitor changes. In particular, the following could happen: when switching from DAC to radio, the code would fail to clear SUM_off, resulting in a weird situation where the main mixer was off (SUM_off) but the headphone where using the main mixer as input. Incredibly this worked anyway (at least on AMSv2 and YP-R0) but resulted in strange volume gaps between DAC and radio mode. Change-Id: I7826835fdb59c21f6483b223883ca9289e85caca
* as3514: fix bug in volume management on AS3543 targets which are not AS3525v2Amaury Pouly2016-02-12
| | | | | | | | | 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.Michael Sevakis2013-04-22
| | | | | | | | | | | | | | | | | | | | | * 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. Change-Id: Ie1df33f1793eee75e6793f16bc7bddd16edb7f75

* Straighten out the mad twisted state of sound.c and related areas.Michael Sevakis2013-04-15
| | | | | | | | | | | | | | | | | | 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. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b
* ypr0: This patch adds radio support to Samsung YP-R0Lorenzo Miori2012-05-28

* Initial commit of the Samsung YP-R0 port.Thomas Martitz2011-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
